Thanks Ricky, don't know about other places but where im going to go ( take other cars there ), they use hunter machine and $150 gets me 5 year "warranty" type thing, so i can go back at anytime and they will redo it /adjust stuff etc. For like $100 is just the one valid for like 6months or something, well worth $150 lol.
