Quoted from frolic:It was approx $350 to add the dmd sized one, so you can take a guess what the "big boy" will cost.
Having said that, because of the modular nature of the system, it is a one time purchase, so I'm inclined to max out my Heighway cabinet since the big lcd will be used with all games.
Would be nice if they gave you early adopters $350 credit towards this..
