We just switched from a Graco infant seat to a Britax Marathon since Bella's getting bigger and I was able to find one at a great price. We love love love it!
Keep in mind that Britaxes are good for 6 years from date of manufacture so it should last you quite a long time!
From another baby board I visit:
Marathon- The most basic model of the three. It harnesses to 65 lbs, rear faces (RF) 5 to 33 lbs. It has a rf tether, forward facing (FF) and rf lockoffs. Has the lever style harness adjuster, 4 harness heights, and the crotch strap does not adjust. It is very padded and comfy just like all the britax seats, and has about a million cover choices. Will last till the child is ready for a booster most likely. Good for children that need to rf still (under 33 lbs).
Decathlon- Harnesses to 65 lbs, rf 5 to 33 lbs. Has rf tether, ff and rf lockoffs. The ff lockoffs may damage seatbelts. It has a push button style harness adjuster, 4 harness heights (rumor is they may be a little taller than the marathon/boulevard), and a three position crotch strap that gives 1 more inch of room as compared to the marathon and boulevard. It has infant inserts so is great for a small baby. It also has a removeable toddler head pillow. It has more limited cover choices than a marathon. Will last till child is most likely ready for a booster. Good for very small babies because of the infant insert but a ma/bv may be a better choice for an older child that won't need the infant insert.
Boulevard- Harness to 65 lbs, rf 5 to 33 lbs. Has rf tether, ff and rf lockoffs. It has true side impact protection (the "wings"). Has a lever style harness adjuster, and instead of having to remove the seat from the car to adjust the harness height you just turn a knob on the side of the seat, and it does not have an adjustable crotch strap. It has a removeable infant pillow so is also a good choice for a very small baby. Will last till the child is most likely ready for a booster. Good seat for any child. Especially one that will have to be on the side of a vehicle without side curtain airbags.
Britax Regent (used to be Husky) KING of car seats is right! Harnesses to 80 lbs. Top slots are 20 inches. Requires a top tether after child is 40 lbs. (unless using a lap-only belt, then it’s required at 50 lbs.), but a tether should really be used all the time. Retails for $220-$260. Not good for children under 2yo. It is FORWARD FACING ONLY.
Britax Frontier For children over 2 years of age and harnesses to 80 lbs. Top slots are 18 inches. Tether not required, but recommended. Harness height is adjusted on back of seat, but there’s no rethreading of harness required. Has a flexible LATCH strap with typical Britax push-on connectors. LATCH may be used when seat is in booster mode. Has 3 crotch strap positions. Nice padding. A 9 year expiration! Deep cupholders that can disappear into the side of the seat when not used. Can be installed with the seat belt using the short belt path or long belt path. FAA approved when used with harness. Converts to a good booster with no weight limit. Replaces the Parkway and Monarch. Retails for $279. FORWARD FACING ONLY.
Have to include my plug for extended rear facing (ERF) and extended harnessing (EH):

Rear facing in Rear end collisions
A childs' vertabrae do not fully fuse until 3-6 years old. Before then, he/she is at great risk for spinal injury. When rear-facing in a crash, the forces are spread out among the strong carseat shell and baby's strong back. The harness holds baby down in the seat and he/she is cradled and protected. When forward-facing, the harness holds babys' body back, and his/her head flies forward violenty, putting tremendous stress on the neck.
Here's the catch...the spinal column can stretch up to 2 inches, BUT the spinal cord can only stretch up to 1/4 of an inch before it snaps and baby is gone. This is referred to as internal decapitation. Babys' head will be slumped over like he/she is sleeping.
It's very important to keep babies rear-facing to 1 year AND 20 lbs. (both, not either/or) at the very least. It's actually much safer to rear-face to the limits of a convertible carseat, as recommended by the American Academy of Pediatrics. A forward-facing child is 4-5 times MORE likely to be killed or seriously injured in a crash than a rear-facing child of the same age...not a risk I'll be taking with my babies.
Check out this video for some great information and crash test footage...you'll see the HUGE difference:

Extended Harnessing (aka EH): Why you should consider keeping your child harnessed past age 4 and 40 pounds in a car seat with a higher weight harness.
A younger child doesn’t have the mental maturity to understand that s/he needs to stay still in a booster. The shoulder belt must always stay on the shoulder to keep the child from being thrown forward in a crash. A parent who prematurely moves a child into a booster is often put in the position of constantly reminding (nagging) her child to stay in position to stay safe. The child will eventually tune out the parent and the parent will become frustrated. The child's safety is placed in the hands of the child. A car seat with a properly tightened 5-point harness allows a child to be a child: no nagging to stay in position, no worrying that the child doesn't have the seat belt on or is leaning over to pick up a toy.
5-point harnesses spread crash forces over a larger area and there are 5 points of protection on the child vs. 3 points with a lap/shoulder belt (1 shoulder and 2 hips). A properly adjusted harness is more likely to keep the child contained in the seat and not ejected, especially in a side impact or rollover. Sleeping is easier in a 5-point harness than in a booster.
Compare these 2 videos and watch how the dummy moves in each:

This is of a harnessed seat similar to those sold in the U.S.

This is of a booster seat similar to those sold in the U.S.
There are higher weight harness seats in all price ranges and some convert to boosters once kids reach the weight limit of the harness.
