Quoted from Phbooms:

with a quick search looks like original is 355lbs and remake 287lbs.

Quoted from conester:

It depends on the individual MMr...I played some at Expo a couple years ago and they played just as good as my MM, but then I played a couple of individuals MMr's and they didn't play well at all. The difference was that the flippers were not strong enough on them! People are so afraid of breaking something by having flippers turned up properly that it plays like crap. In this respect, my MM plays A LOT better! Hell, even different MM's can play differently....I've also played some MM's that played like crap, just because of the way they were set up. All depends I guess is what I'm saying. Properly set up MM and MMr will play the same.....but that's not always the case. I've been told many times that mine is one of the best playing MM's and I tend to agree. If you ever want to play it, just come to one of the shows and it will be there! LAX, Ohio, Expo...I bring it to all those. I do like the new animation on the MMr better than the original though.
