I'm thinking OP means EM and it autocorrected to "Embassy".

He had another thread where he considered a Zizzle, and was correctly swayed from doing so by the Pinside community.

OP - I'd recommend setting up a basic Craigslist search and then saving it as a favorite webpage. I find that more EM's are listed on CL than here on Pinside... but it may be different in your area as my Pinside and CL searches are based on up here in the Northeast.

A search of "Pinball" with a cap of $750 (knowing you can always negotiate down on CL prices) brings up a few results in the Detroit Metro area. I'd just search daily and when one comes up in decent working condition and good value, I'd pounce on it before anyone else can even get eyes on it. There are also some light cosmetic project early Solid State (SS) games that may come up in that search as well. I just don't know the Detroit pinball market at all but I wouldn't be surprised if a well playing but dirty Flash or something pops up.

Patience is key. Waiting for the right machine >>> buying the "right now" machine.
