I'm not knocking the quality of these parts, but I think I'd be willing to spend even more if the quality reflected the price. Two of those rims would be about $100, and the hubs max total would be about $250. With spokes, that total looks to be in the $400 range. I'd be willing to drop some more.

Then again, if I keep the price lower, I can save up faster...
That was an ah-ha! moment for me.
