I played both of the MMRs at TPF this year. I thought the standard played poorly but the LE played better than any MM I have ever played, original included. These are still pre production models so I'm sure the standard just needed adjusting.
The lamps are beautiful on the remake. I dislike that they're integral to the board. You'll have to send it in for a burnt bulb unless you're handy with the soldering iron. People who like to customize lighting will be disappointed.
In the end, I'm pretty sure it will be pretty close to the original. It's up to you to decide if it's worth the scratch. Personally, I think there are better Bally/Williams machines from that era that play better and are much cheaper than MM. I do love the theme, but original or remake, I feel like thes game should be in the 5.5-6.5K range.
Until They fall into that range, I'll be content to play it once or twice a year at the events I attend
