I know absolutely nothing about stringing machines, stringing or raquet modification. I use Wilson nxt tour on my raquet because my pro said it's a good string and is resonably priced. I break about a string set /month. I have a daughter that also plays in High School. She doesn't break strings often but usually gets a string job about every two months due to fraying and tension loss. I have another daughter in Jr. High School who started playing last spring and is already talking about playing when she gets to high school in two years. It costs me $35.00 every time I get a racquet strung. So at about 20 string jobs per year I'm spending $700.00 / year. I've been looking at the string only prices on TW. It seems to me I may be able to save some money if I learned how to string. How difficult is it to learn. Are there stringing schools you can attend? Who taught you guys how to do it. Can you get a good string job from a machine priced at less than $500.00. How long does it take to become proficient? A little guidance would be great. Thanks!
