I recently picked up a 5 yr old Giant TCR SL 0 with Sram Red 11 speed, new cassette, chain, cables, tires, etc for <$2000. The quarq power meter eats batteries (I think it has a short) and is out of warranty, but for the price I don't mind. I upgraded to the Favero Duo pedals and haven't looked back. IMO the 3-5 yr old market is where the good deals are, unless you are sponsored or just want the latest and greatest.
