My LBS has a used Cannondale T800 touring bike on sale. I think it's a 2005 or recent year model. It looked like it was in excellent shape. It included fenders, a rear rack, and a trip computer. I don't know details on the components but the bike looked like it wasn't very heavily used.
The bike is too small for me, but I thought it might make a good bike for my wife. Currently, she has a mid range Schwinn mountain bike, but I think she'd like something faster. She is interested in a road bike, but I think a touring bike might be better suited for her interests since it would make a more comfortable commuting bike, plus the lower gears would be helpful for the hills near where we live.
The bike is listed at $650. Does $600 to $650 seem like a reasonable price for a used, but excellent condition T800? Assuming it fits her, I think this might be a nice bike that she could use for commuting, fitness, and touring.
