ride the bike, wait for a cheap wheelset to appear on craigslist, then do this.
if you can get a wheelset with tires, cog, lockring already on it, you could save a lot of money because then the only thing you have to buy is chainring bolts and a chain.
edit: You already did this, most people would have bought a Kilo TT but I am a fan of putting together your own bike, even if its with cheap parts.
