It's probably the W/B DMD that I've liked least out of all I've ever played. That being said, I only played it 3 times. For a grand I'd take a chance and add it to my collection. I've had strange thoughts about trying to mod it and make a totally clear upper playfield (not just the existing circle window being clear, the whole thing) and adding a clear section to the blue animal ramp that obscures the left outlane, making nudge saves impossible.
I'd like to toy around with one.
