" buy motors that cost that much..luckily, it's not out of my pocket...:-)

I guess that is pretty much how it goes when dealing business to business. I decided once to make a SOTA turntable for myself so naturally the first thing I looked into was the motor. Now I said to myself that I need a truly zero cogging, constant torque motor. Then I found some high precision rotational stages with a zero cogging motor as part of the platter itself. Add to that they had magnetic bearings and very flexible speed range. Prices for this platform started at around $15,000 + another $3000 or so for the controller. Then I looked only at a motor of that type, $10,000 + $3000 for the controller. Gulp!
I was recently talking with guy from Australia who makes this ultra expensive Contiuum Caliburn turntable ($90,000 retail...Yikes). He told me that they spend $8000 for the motor alone on that design. A year ago I would have laughed and said there is no way a single electric motor can cost that much. Now I know better. If you want to make a consumer product with real research grade parts it would cost a fortune.
I was also looking into making equipment racks from optical breadboards and research grade elastomeric feet. The specs were very good and it would have made superb vibration control. However; a three shelf rack woud have cost ME over $3000. Now think of trying to make a commercial product? Not too many audiophile takers for a $12,000 rack but in my lab in grad school this would have been purchased without batting an eye (hell we had full blown honeycomb laser tables on air suspension that were nearly $50,000 and lasers for over $500,000 so $12,000 was no big deal).
