I did some searching about boosters, because we may be moving to one soon. I can't remember where I got this list, but it was from some site on car seat safety. i think i'm going to get the graco turbo booster.
sorry about the length of the list! i'm just glad to share!
The best bets for proper positioning of the seatbelt - which is THE MOST important thing - in booster seats were:
graco turbo booster backless with clip
fisher price safe voyage backless with clip
combi kobuk backless with clip
britax parkway and monarch
laroche bros. teddy bear
safeguard go backless with clip
volvo booster cushion
recaro young style
