You can get the X-1 for $135 shipped... Without blemishes. It comes with all the tools and some string, just like the Kllipermate.
It really has a quality look and feel to it. There is a Gamma rep and a ton of owners all over the board.
The instructions with the Klippermate are better, I don't think too many people will argue that. The Gamma does come with a stringers guide though which is extremely useful. It goes into great detail about stringing, installing grommets, and knots.
Supposedly Gamma is going to update their manual
I guess you really can't go wrong with either one. I just like the cost and look of the Gamma a little more...
