Quoted from valgalder:
Yeah, from my experience, all the MMr i've come across play pretty horribly also. I'm sure there are ones out there that are dialed in correctly to match the original, but unfortunately not the ones around here (especially Logans, ooof!) The AFMr are definitely hit or miss, but I think it's more of a setup thing. MBr that i tried at Expro played really nice (besides the one with the flippers set completely incorrectly). I don't know why so many of these Chicago Gaming pins have the flippers positioned completely wrong out of the box. I didn't think that should be something that would have to be adjusted so drastically.
All machines have variability. The MMs remaining out in the field around here are terrible. I've owned a few MMs, and my MMR is even better than a high end restoration I bought nearly 15 years ago. MBR is gonna be amazing.
