One machine I absolutely love is Teenage Mutant Ninja Turtles.
I love the backglass artwork and the cabinet artwork. The audio is excellent cranked up. NINJA NINJA !
The gameplay is fun and the flow n shots are straight forward and really really fun.

Pinnys like this, show that some other DMD 90's machines are just too complex sometimes. TMNT is not a expensive machine (say $2500 for a v nice one) but they are getting harder to find cause people are hanging on to them, cause they are fun for both kids n adults. You dont have to spend 6 or 8 grand to really find a hugely fun pinball machine. Star Trek Next Gen is another for under 4 grand which is also superb, and being a widebody, u get that limousine feeling when playing it. Nice for v reasonable money !
