What did you expect bro?

Find you a good pro shop and suck up the labor costs. Otherwise you'll never have a straight shooting bow. You can and will find some good people at big box stores... but you just never know. There are hacks at pro shops too.... but you don't have the high turnover that you'll find at big box stores. Most pro shop owners that have made it and been established have reputations to go with them... Just ask around in your area... you'll figure out who to trust pretty fast.
