I just picked up a sample Funhouse for $1700 not working. Turned out every fuse in the game pretty much was toast. Booted right up after that. I'd pick 1 also. I have seen games with clear coated or repro playfields installed recently for the same price as your 3K router. From other posts, looks like you can no doubt put it back together again.

The sample game is the same as the production with a few differences. The only games that have s-t-e-p-s are prototype games(10 of these). I just picked up a sample and the differences are the Side rails are system 11 rails, The start button protrudes, and there is a hybrid system 11 sound board setup in the backbox because they were switching over to WPC as Funhouse was being produced. And lastly the samples were coated with diamond plate. I think thats all the differences, but I could be leaving something out.
