Which tennis string should I get?

I need a good tennis string for my racquet that offers durability the most, control, power, and a little bit of spin. I break my strings around once a month and I can't afford to keep driving an hour away and pay $30 bucks for re-stringing, so I need a good tennis string to use. My favorite string that I've used is Prince Topspin, but it just doesn't have the durability. Thanks for the recommendations!
