1) At those prices, you can probably resell the other two..
BUT
ONLY MAME THE WRESTLING GAME!
The space invaders one will probably be pretty easy to fix. Hopefully it will be something simple. This will sell if you can get it working for a few hundred easy
The pacman machine, if you can get it working, will finance the entire thing. Sure its not as much as a mspacman... but you will get some cash out of it.
So if you have the space.. Bid on all 3 and assume you will get a few hundred back on the non-mamed machines.
