Price is dependent on your area and the demand. I can only speak for California. As the poster above mentioned, there are lots of Lemonds on CL advertised here at pretty high prices, I have seen some asking as much as $900-1000, but they simply don't sell.
I guess price also depends on how much patience you have. If you are willing to list it a few months, you might get a better price, but in California anything over $400 will be a tough sell. $350 might bring some offers. It's a tough time to sell old bikes. Ebay will give you the highest potential price, but shipping costs will eat into your profit. If you are determined to get maximum price, that's where you will need to list it.
I would note that the frame is Tru Temper and not Reynolds 853, which decreases value. The condition is excellent though. Good luck.
