I have been able to get my parents permission to purchase a stringing machine. I have been playing tennis for 2 1/2 years now, and i think now is the time to get a machine. I just had a few questions. 1.) How much are string machines? I'm gonna be a first time stringer, and would prefer something cheap (really cheap), but reliable and accurate. 2.) How long does it take to learn? 3.) What specific models would you prefer? And would you reccomend getting these online? If so, what site, and if not, where else?
