Thanks for all the help, but after much soul and economic searching, I think I'll just have a new frame and spokes built around my 105 rear hub. The hub seems to be in good shape, only the rim and spokes really need to be replaced. I talked with a local wheelbuilder, he says he can do it for a little over a hundred buckes, with Velocity rims and double guage spokes.
I definetely want to go with velocity rims, they look like much better quality than Mavic.
