I have it in my Monster Bash and ST:TNG and they are both fantastic. I've got the MMR colour and its awesome.
But I"m planning to order the new ColorDMD LED versions for my machines when they come out though, it looks so much better and original, the LCD one when in dots mode is great but the LED I really liked. The ColorDMD guy said that LED and LCD screens will support all machines (although the LCD won't fit in some). I've got an LED on order for my Ghostbusters which runs single colour at the moment but rumour has it colour is coming.
The good news is that you can get one and they are movable between the same pin manufacturer or you can order the cable kits to move them between manufacturers. ST:TNG is a good choice in your machine line up though!
