...and "Vampire Kiss" was on the 7620, with the Edge.
If it's a 7620VK and if it's in decent shape, that's a great price. The blue book is off bass, but even still e-bay prices on 7620's have recently gone up a bit - $500 is no longer that uncommon.
7621 (
fixed bridge) it's probably a good price as well. For a 7420, 400's towards the upper limit for a player. See if you can talk the seller down a little bit - $350 would be a little more fair, IMO, if it's really in quite good condition.
