ProAudioStar has some open-box Deepmind 12s for $649 - I could NOT resist at that price (as I was looking hard at the Deepmind 6 in the same range, but well, if I can get the whole shebang for that)...
Will report back when it arrives.
Link for those with a sudden need for a few hundred off a 12 voice poly synth.
