TT/Tri bike Recs

I'm looking for a good TT bike, definitely used though as I dont' want to spend a lot. I want an actually TT bike with TT geometry, not a road bike with bars and an extra seatpost, saddle, etc. $1000-$1200, 54-55 cm. Anyone know of anyone selling something like that?

Try this website, http://www.preownedbikes.com/preowned/, they have some bikes under $1000.

Also try a few of the triathlon forum sites, they have gear swap thingies just like us
