I was looking around at the various entry level stringers (around 200$) to start myself off with stringing and had decided that silent partner string seemed best for me. From what I have read, the two positives of klippermate and gamma x-2 are clamps and tension mechanism. The silent partner has good clamps and a good tension mechanism, and also has a (almost) 6 point mounting system, which for me would justify the little more it cost. However, I tried to find one online and couldn't find it. Even their sight didn't have it http://www.sptennis.com/stringer.asp . Is this machine still sold?
