Quoted from PanzerFreak:

They have made some great games but at the same time have cut corners and raised prices. I love my MET Pro LED that I just bought but Sterns decesion to remove service rails, change the back box lock system and use a different mechanism for the lockdown bar on pros leaves me scratching my head. $4700-$5k for a pro is a lot of money and there's no reason they should be lowering manufacturing costs with the items I mentioned. At least they are including LEDs in pros now.
Also, its time for Stern to start including ColorDMDs in all games going forward with no price increase. It's 2015 Stern, if you are not going to use an LCD in the back box then include a ColorDMD to justify your prices.

The ball moving along the back board in the game Kiss is one as is many Innovations. My favorite is the ship in POTC

Quoted from Radius118:

Thank you for that link. Dang it! That's almost exactly the idea I had in mind. Someone beat me to it.
Yes, that's the idea. It's the pressure from the edges of the legs against the cabinet that causes the decal issues and gouges into the cabinet.
So Stern is using these on their machines now?
