SuperAuctions has posted their Summer/Fall/Winter auction schedule. I have gone to many SuperAuctions events in the past ... sometimes you can get a good deal, sometimes you have to watch your back for fake bidding. Both of my Neo Geo cabinets have come from SuperAuctions events for less than $200 ... of course, I can't remember if that included the 10% buyers fee and the 3% credit card fee ...
Check out the schedule and see if there's an auction coming to a town near you. If you're planning on attending one, be sure to respond here and let us know! I'll be at the August 14th one in Texas for sure!
