I called the first bike shop back. The rim they told me about is spokes, nipples, hub and everything included. So that sounds like a probabal idea, for 40 bucks with the time I have left to find one it sounds like a good option.
I called the first bike shop. They're oddly enough only open on Mondays, Thursdays, and Fridays... so I'll go there tomorrow morning after third shift lets out and check it out. I have a feeling this 2nd bike shop may have more of what I want, and possibly already in black as well.
But regardless, the first bike shop has the silver rims, hub, spokes, nipples, etc already assembled for 40 dollars. I just hope that if the 2nd bike shop doesn't have what I need, that the 1st bike shop with the silver rim has some in stock! With my luck I'd go in at the last minute before I go to SC "Uhhh, sorry.. that man over there? He just bought the last one."
