I probably wouldn't go more than $300 on the 560. The overhaul makes it worth it, but there is some light rust on the chrome and scratches and oxidation on the aluminum bits. Still, Suntour Cyclone is nice stuff.
The Cannondale is a late 90's frame. Sounds like it's been upgraded to at least 9 speed (was the Ultegra name is use during the 8 speed era?). Depends on the condition, I suppose, but mismatched crank arms? Sounds like it's been ridden hard based on the seller's description. I'd be tempted to offer something closer to $200, unless it's in better shape than I think.
