Single player EM are generally going to offer a deeper game play because they were usually designed to complete a certain task(s) over 5 balls as apposed to multi-player EM's which usually reset all sequences at the beginning of each ball. There is a learning curve to EM repair, but thankfully there are some great online guides and repair support. If you are thinking about an EM, read the instruction card to understand the game...watch some videos. As others have mentioned, it might be better just to pick up what you can find locally if it fits your budge and it's in nice condition. Do not rush, wait for something with nice backglass and playfield. Watch your facebook market place and craigslist for games...check a couple times each day until you find your deal.
