Zaxxon is a good game, but don't expect many - if any - takers for $450. I sold mine a few years ago and struggled to get $400 for it, and it was in better shape.
Realistically, I think you should be able to get $350 for it, but not much more. It also doesn't help that it has that hideous, poorly installed start button on the front. Ouch!
ill give that zaxxon a good home, poor unwanted thing! i have a 60-1 but its not the same as ur. ill have me some real zaxxon now. ill nickname her big zertha!
gonna put some diamond plate on the front of that thing and make it look cool!
