I know people constantly post asking for advice on a machine and I'm just one more but I'd love to hear from the forum. I'm interested in buying a relatively simple but high quality machine for family and friends. Probably only 5-8 racquets a month so don't want to go crazy. Had decided that a fixed clamp drop weight was going to be fine and I really like what everyone has said about the Alpha Pioneer DC Plus but I just heard from them that they are back-ordered until June which is after the high school tennis season (where my sons break a lot of strings). Anyone have any success with any of the European brands (Pro's Pro or Penta)? I know Gamma is an option but they feel a little pricy for what you get. Are Craigs and the bay the best angle on used... there's really nothing there now? Anyone have any recommendations?
