If the ergo levers are properly functioning its a $250-ish bike.

Look at it from a parting out perspective. What can you get for that bike parted out?

Conservatively:

F&F: $50 to the fixie crowd.
Wheels: $75 w/ tires Mavic rims and Campy cassette hubs
Ergo levers: $75
FD: $10
RD: $15
Crankset: $25
Brakeset: $25

There's $275, conservatively, without accounting for other misc. stuff.
