The EM machines are still sub $500, it's the solid state and DMD pins that more costly. That's because EM's take much more maintenance to keep running. Chance, if you don't have one yet, you'll need to pickup a leaf adjustment tool and a points file and a can of "Super Lube". Anything that has a bushing should be cleaned out and re-lubed with Super Lube. The grease that was used in these older machines dries out over time. I have 2 EM's, Klondike and Flipper Clown. The Klondike is pretty good at working 100%, but the Flipper Clown... you have to fix, play and never shut it off. It seems to break if it's off for a day or more.
Good luck
