Hey, i'm in need of some new clamps for tuning my skis, and skis of my customers. I decided that instead of washing dishes at the restaurant up the street, I'll tune skis for a fair price. But i've been using the clamps my dad has used since he was 16. THe things are crap. But, I have a low budget, what would you recomend that I buy to get something better, and for a good price?
