I have an original MM that I bought in 2000. Rebuilt it then with a NOS playfield and many other NOS parts, ramps, etc. Since then I've added a shaker, colorDMD, the 3D translite and mirror side rails to it.
When it's properly tuned up, it plays TONS better than my friend's MMR that he bought NIB.
There is just something about the remakes that they just don't have the same feel, the same play that the originals do.
Find a nice original and play it yourself. It's a very fast, fluid game that's considerably easier to service than the remakes.
