So, this year I'm getting a xmas bonus from my work and instead of saving it, I'm gonna buy myself a bike frame...I'm looking at the following:

Bikeisland Track Frame + nyc fork
Iro Angus
IRO Mark V Pro
Kilo tt (I'm already riding around on a conversion with a decent converted road crank and cxp22 from bicycle wheels.com..I could take the extra stuff and swap it or sell it or make my girlfriend a bike)

which one should I get? Just tell me..also, i'd prefer a threadless system but it's not a big deal if I don't.
