Least expensive HBB with LATCH? Am I right? Quinn prolly be outgrowing his FR85 in about a year, maybe longer. But he has been booster training with me since he was 4.5 and doing well. So I'm considering switching him in Grandma's car after this winter (so he'll be ~5.5). Even at it's price it's something I do need to budget/save up for, so I want to make sure I don't miss anything less expensive.
