So I found a guy selling a TON of tennis stringers again and he has a Winn Pro 2 1000 stringing machine for $150. He didn't give me much info about it but he said it looks very similar to the Gamma 6004. Is this a good deal? If not i can just look at his other ones, they are all under $250 he said. Anything bad about the stringer? Thanks. PS : The guy used the stringers for racquetball. If that matters at all.
