I have a Britax Marathon and I love it! My step-sister originally let me use hers, and when it expired, we bought a new one. They are more expensive, but they last a lot longer in my opinion specifically because of ease of cleaning and use! My neighbor buys a less expensive brand, and when they get dirty, she buys a new one. I think she has already spent more on 3 car seats than my 1 Britax Marathon. I would recommend a replacement cover in case of "baby accidents". With the Britax Marathon, you can start with rear-facing and then switch to forward facing when ready.
