Ditto, just fix the spoke. I bought a bike with crap wheels, and I just replaced spokes until I got to about #14 in a year. Then I gave up, bought a new rim (Mavic something, MA3 I think) DT butted spokes and sat down with Sheldon Brown's wheelbuilding page and had an interesting evening. That wheel never broke a spoke, the axle finally broke about 12000 miles and 3 years later.
