It's definitely more fun wanting, waiting, searching for a MM then actually owning and playing one. I bought this one 2 years ago this month for $6500 and it was in great shape, had to put a little TLC into it.

I love the artwork of the game and the theme, but found it to be more of a collectors status pin or dick swinging game more than a great player. Realized I had more plays on my LOTR than the MM in no time, and decided to sell it.
Out of the main Eddy pins, Shadow is the best. I consider AFM a better player with longer legs than MM too.
I think the castle is one of the best interactive toys in all of pinball, it manages to slow the game down though compared to the AFM saucer. It may be equally repetitive hitting the saucer over and over, but that castle gate is a snoozer in comparison when it comes to ball action.
