All of these games were "less than a topper", well under $750. There are still a few out there, EM and early SS. Less than $4k total for these 10 games. Of course, I've had to work like a dog to get them all working (Pinball and On Beam getting close).

@nhpolarbear: Sorry, didn't see your comment 2 months ago. Thanks for the compliment on our collection. I've been playing pinball for something like 46 years, and owned a few games (1 or 2 at a time) in the 90s and early 2000s. Fast forward 10 years, and we moved to Piedmont, WV (a decrepit town in a beautiful natural area) so we could have LOTS of space for cheap.
We only live 100 miles from CoinOp Warehouse in Hagerstown, MD, which has proved dangerous! There have also been a lot of machines that we have found (mostly on Pinside) within a few hours of here . We have filled up quite a bit of our space with games.
We only had Jungle Queen when we moved here in 2012...we now have 19 more machines. All of them are working except Pinball and On Beam, and those are both close.
We're hoping to start up a monthly tournament here soon, with a "Pin and Breakfast" option for long-distance travelers. I will post on Pinside when that is ready!
