I know people often say, buy the best you can afford, but there is a point of overkill for the average home stringer. And as you go up in price, you don't necessarily go up in speed. So with that said, what stringer would you recommend for fastest, most efficient string jobs that are of course consistent. That factors in ease of mounting the racket, how quick the clamps are to operate, etc. I assume it would be some self-centering mount machine with an electronic linear pull? Recommendations please! Thanks!
