I'm about ready to purchase a booster for my 4 year old and am looking for, what seems to be, the impossible --- a "high" quality booster with LATCH. I am extremely interested in the Jupiter Komfort Kruiser (with Graco Turbo and Britax Starriser Comfy a close 2nd/3rd). Is there anything on the market that is similar to the KK that has LATCH (and 5 pt harness that converts to use a seatbelt would be nice too)?
