Just picked up a NIB Met Pro LED a couple weeks ago. My first NIB and the first Stern game that I was willing to sell one of my classic Bally/Williams games for (sold my TAF). I wanted to add a really fast "adrenalin rush" game to my lineup and Met totally fits that bill!

My only concern is that the build quality of the modern Stern games, especially The Pros, is pretty low. Cheap plastic apron, no service bars on the playfield makes it difficult to prop up the playfield to work on it, and easy to ding the inside of the cabinet when pulling the playfield in/out for maintenance. Lack of appropriate playfield protection (my drain hole is chipping after less than 100 plays), etc. Of course, with enough $ these things can be rectified but something to consider going in.

Also, my inserts all have a ton of grazing which makes them appear more opaque and not clear, which bothers me enough that I wish I'd bought used HUO instead and found one that was clearer (I've seen others that don't have the same issue). Posted a thread about it: https://pinside.com/pinball/forum/topic/is-my-nib-metallica-pro-playfield-defective

Also, some others have reported serious defects in their clearcoat with recently produced games, you might want to consider a used machine you can inspect before buying (unclear at this point if Stern will correct these issues): https://pinside.com/pinball/forum/topic/hey-stern-are-you-serious/

But, all that said Metallica is an incredible pinball game, amazing rules and lights/sounds/dots, lots of different strategies available, try for max points, to see the wizard mode, or play other "side modes", stackable modes and multiballs, fun and rewarding shots, etc. etc.
