Toddler car seat recs?

bobkitten

My 5 month old is outgrowing his infant carrier/car seat.   We're thinking of moving him in to the Britax Boulevard that his 3.5 year old brother is in and getting another convertible/combo car seat for him to use.  

Any recommendations on good seats for the toddler to booster phase?  I would prefer not to spend $300 each since we need to buy 3 for various family vehicles!
