I'm in the same boat (literally- got hit the day before my birthday at the end of Nov though).

I like the Colnago Sprint, but cheaper is Motobecane Team Track from BD.. full dura-ace w/ deda bits.

for the 2500.00 budget, you could buy the Colnago Pista Frameset and and outfit the Colnago with full dura-ace for a 13-14lb bike. This is what I might do.. or buy the team track and ride it until I find a frameset I like (mercx has my eye too).

Not really sure what to do. Anyway, hopefully you are ok? I had a fun ride to ER, but am pretty much fine other than some road rash that seems to not want to go away.
