I've played it a couple times... I didn't think it was that much fun. I wouldn't pay or trade much for it... since you've never played it, and are worrying mostly about value, I assume you're just gonna try to flip it?
Maybe you could find the right buyer at $1000 if you held onto it for a while, but if you don't want to be stuck with a large machine for months, I'd guess you could fairly quickly get a couple hundred bucks out of it (based on gut feeling and no actual data... other than comparing it to Super Chexx or Air Hockey, it's not as fun, and not as popular... so probably not as easy to find a buyer, or worth nearly as much).
