Booster recs for My 8 year old

Juliannas turbo boooster back broke .... AGAIN.. the head rest just falls right back down when I pull it up, she rode to school with Keith and said she felt like she had to hold it up.. he thought she was complaining cause she didn't want to go to school... I went to get her and in the parking lot noticed the head rest was all the way down, so I moved it up, and it fell back down over and over, till I had to take the back right off.. thankfully I have the seatbelt guide for a backless in the glove compartment. (of course the belt did not fit her shoulder nicely with out the back but we made it home in one peice)

Soooo of course the turbo booster is out of warrenty now, so I have to replace it, and I was thinking of just getting something different all together, this is the 3rd time in the 18 months I have had it that this has happened, (the last 2 the back was replaced by graco)

What do you recommend? I like the looks of vivos but what else is good? in my car she has an old style parkway that I like the fit on. (I took keiths car today)
ETA more info.. I do not know her exact weight and height, but she is large for her age 75th for height and weight like for years.
We ARE good about buckling the un occupied booster so no need for latchable.

what's your budget? I know the Monterey is a favorite around here

When were the pieces last replaced by Graco? Have you called them again? If they were replaced less than 1yr ago, I'd call again. See if you can get a refund for the seat. I had this issue with A's seat when we first bought it. They replaced the head piece. Then the head and back. Then I asked for a refund because it was still doing it.

hmmmmi will call graco then about it, if I get a refund for it then my budget goes up lol:thumbsup:
