I just bought a 1980 710 for $400. Bike is mint. mavic HD 500 hubs, Mavic ?? rims. Mid 80's shimano deore r derailer, campy front. Superbe brakes, Nice SR cranks, one of thos technomonic[sic] riser stems, brooks wide seat, really wide bars -nitto. Bike had very low miles-guessing under 200 :-) Made out of 531 tubing and room for bigger tires. It could use some more clearance in rear. Been riding it around for the past week. Very nice ride. In fact it rides nicer than any bike I've owned. Love it.

I'd say find someone who will appreciate it and make them a good deal. I got mine in person. One ride and i was sold. I wouldn't have bought off ebay. The ride got me to part with my cash. CL local buyer.
