I initially bought this machine to restring my racket and my sons every week and it has been great, easy to operate, etc.... Now I'm starting to pick up a few other rackets from other players.. I may go a few days with nothing to string and then have 2-4 to string. Would moving to a similar machine with a crank tensioner help me time wise and are they as reliable ? Right now it takes me close to an hour to to string one racket. I don't really push it and try to take my time. Is it crazy to think there may be someone out there that would want to trade a crank for a drop weight ?
