I'm thinking of buying either the Gamma X-ST or the Gamma Progression ST ll table-top stringers. Both models look very similar and are also similar in price. Anyone know the difference? I think atssports.com has the best deal on them from what I've seen. They give free cover, shipping, and some string with both models. Also, please give any reasons not to buy these types of stringers if there are any. I'm used to stringing on my tennis coaches floor model and it's real nice. If I buy a tabletop will I be dissapointed? I always here people say go for the models with stands but it seems to me if you have a table top stringer sitting on a table or desk what defference does it make anyway? I think it would be nicer because it is more compace and would be more portable.
