I have some good friends who have agreed to go in on a stringing machine. In return I'll string their racquets and make sure they get more than their money's worth in stringing labor. In addition I'll offer stringing services to everyone else (for a fee of course). Not sure how much business I'll be able to get. My history: I bought a cheap drop weight about 15 yrs ago and learned to string. But I have 2 friends who both have Gamma Progression II ES's so I've used that machine by far more than any other over the years. Really only did 10-20 jobs on the drop weight. Unfortunately I don't have access to those Gamma machines anymore. I think I can safely spend $600...maybe as much as $700. What machine would you recommend? Ideally I'd buy a decent used machine. So far not much luck finding anything. I'm also looking at a Gamma Progression II 602fc It's a drop weight machine but I figure I can upgrade down the road with a Wise head or a Gamma electric tensioner (if that's possible). My question, though, is do you think that based on my history of using an electric machine for the last 13-14 years, will I hate the drop weight and regret my decision? I feel like I should prioritize toward a high quality mount and fixed clamps over the more convenient tensioning system. But then what if I end up stringing a lot of racquets? I'd appreciate any advice/suggestions you could offer. Thanks!
