I found out that it's gonna cost me $60 to replace the 9 broken spokes including labor. He also told me that the hub clamped adapter would break spokes too, although not as quickly as the stock sprocket mount would.
So I've decided to just spend the $54 and get this wheel that was suggested to me in another thread:
HUSKY T-124 (pre-2002) Rear Wheel: Husky Bicycles
Here's my question..it says that the wheel requires a 15mm axle, and looking at the axles on the parts page, I'm not sure that it would work with my mountain bike..unless I'm mistaken. I've also got a 5 speed cassette to worry about too.
