Just wondering if the Machine comes with everything I need? even the clamp to hold the tension? Anyways on this video http://www.youtube.com/watch?v=Ygwsrrrj04Q&feature=related He is using an automated puller or whatevr u call it. Is there any video out there that can guide me on how to use this Alpha Revo? I got a feeling that I will be wasting a lot of string before achieving my first successful string racquet.
