Peter,

You will easily find a nice 2 player EM for around $1,000.

Only my opinion - but go with a Gottlieb 

Also would suggest a single player Gottlieb EM rather than a multi player - still she is your call.

If you do go down the multi player path - a 2 player is the way to go. The 4 players are double the effort to get working properly (if you buy a project)

Ask all the questions you want, glad to see you have seen the light
