@ $30k its beyond most but I recall the New England Digital Synclaviar was about $50,000 in 1984 depending on the model.
That was the cost of an entry system, a full blown Synclaiver could cost you up to $500,000, I think Frank Zappa had the largest system made. BTW I might be getting my hands on one soon.
I saw the Schmidt at the NAMM show a couple years ago, its nice but the cost is high because they are hand built one at a time. I think the price went down a bit to around $20k or so. Maybe we can group order a few and get a few $k more knocked off the price.
