We have the recaro and love it! My son is now three and 1/2 and he is still in it comfortably.
There are comments on the recaro site about the straps twisting, and I was worried about that. It does happen to the one in my car sometimes, but doesnt happen to the one in my husbands car. Although, mine gets used a lot more than my husbands. The twisting doesnt really bother me though, just takes a minute to un-twist.
I think for the safety and the basis of who this company designs for (race cars) that any twisting I have to deal with, with the straps, doesnt outweigh the benefits for my child.
I would buy recaro again if I had to get another seat.
Good luck to you! And congrats for thinking outside the box and for considering something other than the most popular name brand!
