This place has some CHEAP hubs. $50 for the rear 105!
Find a Deep V on line for $60, maybe $70.
Then after ou get the parts, go to the shop and have them build it for you with new spokes. Be sure to hacve it retensioned after 200 miles or so ( no matter what the shop says, do it!)
32 hole hub on that site but with a Deep V and a good build, the 32 hole will work with your weight. If you want a better wheel for less than that, prolly ain't gonna happen!,
.............I have abotu 15,000 miles on a 28 spoke Deep V that I built (240-260 lbs)
