I have a Pro's Pro XP Plus stringing machine (like this http://www.racquetsolutions.co.uk/product.asp?P_ID=411) which I am looking to trade for a desktop model. Mine is in 7/10 condition, well used and marked around the stringing turntable area. It has been well used and in the 3 years I have had it I have replaced both clamps, 2 support arm, 2 racket supports and 1 clamp base/bar. It serves me pretty well but is quite big and ugly! I am looking to swap for a desktop machine that is either crank or electronic and in a similar age/condition.
