Breakshot was a modern interpretation of EM game play. I'm not sure you could get much closer to true EM for a reasonable price. I would guess that most of the hardware to run an EM would be specialty at this point, and therefore expensive. But I think a game like Breakshot could come in under $3000 today, especially if you skipped the DMD.

I'd like to own a Breakshot, it's just a little too mature for my house. I always look when they're for sale and think about it though. With so few specialty parts, it shouldn't be too big a project to make a similar game new. I think the challenging thing would be finding a good reason to spend money on a new EM when there are so many old EM's around.
