I would say so, unless, of course, you have a hidden skill in wheel building. Wheel building generally costs on the upper end of 50 dollars (where I've been at least). A new hub will cost you a fair amount, and you'll probably need to get new spokes too, and then there's the wait -- oh the wait.

Chances are, the wheel you're getting is nicer than the rim you have already. One other thing -- I recently ordered from the bikesmiths, and they get two 's from me.
