I did some research on here a while back about stringers. I was set to buy a Prince Neos used, but could never find one locally or on a reputable site (i.e. tennis machines). Their price new does not seem like a great value. My local stringer is raising prices and his customer service has gone downhill, so I am revisiting purchasing a stringer. I am thinking I'd like to purchase the Wise constant pull tensioner as well. Given it's been a couple years since my research, I know there are new models out there now. What recommendations do you guys have and why? Thanks in advance for your help!
