Ok so I am currently a highschool player and I do not know much about stringing racquets. I break strings often and I am starting to think about stringing my wn raquet. But I am afraid that i might be bad and crack the frame or some kind of accident might happen. So i was wondering if I am capable of doing this by myself or i should not bother and buy thick polystring and live off that. Also i know there are variety of stringing machine out there and they are all made for same purpose but... Do they string the same? Is it okay to buy a cheap machine?
