Under 600$: Your choice in bike
 

I was doing the normal bike day dreaming that occurs when you are doing something you are not enjoying (for me, studying for finals) and I wanted to see what everyone's choice in bike would be for under 600$. This would be a race capable bike and I would assume used. Make your choice reasonable in that it would not be super rare to find the said name and model at that price. I am interested to hear everyone's choices as I may end up buying a cheap bike for a training bike.

Bianchi Pista Track bike, damn I always fight the urge every pay day to buy this bike on sale at my local LBS.

For $100 more, you have a massive, years-long thread stickied at the top of the forum. :D

FG/SS bike. whihc one? that's another question.

Used Al frame, Ultegra 9-speed, CF fork. Should be lots of options out there for $600..
