My sister is having a baby and registered for a Britax marathon. I know it's a good seat with a nice high price tag, but is it really the best seat she could get for her money? How does a first years true fit compare. I thought I had read that the true fit had a simple one hand strap adjust but I could be wrong (is that another seat?). I'd like to suggest to her an alternative so that she can better spend her money. Any suggestions? We are in Canada.
