Master Sports use to be the distributor of the SAM stringing machines, and when they gave up their distributor to xtremesportsmachines, the SAM in Ft. Wayne were selling off all their machines on the big auction site, as that was how I purchased my Pro Master machine. It was brand new, sent from Ft. Wayne, just no warranty was all. Been a fantasitc machine, as I was going to purchase a Star 5, but when this came along, it was way worth my while. For what I paid for this machine, I was glad I did not get the star 5, as this fits the bill for what I needed.It holds the racquet solid with its mounting system, the electronic tension head pulls spot on every time I checked it with a calibrator, even though it is self calibrating, and the machine makes stringing a pleasure.
