Mike, having no data, my logical guess would be that you already know the answer. No demand.
Just because 3 or 5 people are willing to spend $2000 for a brass T1 doesn't mean that several hundred would be
willing to pay that, or even pay $1000. It only takes a handful of people who really want something
badly to drive up an eBay auction. If brass T1 after brass T1 came up for auction, say, 100 times, and always
brought that kind of money, then I'd say there is demand.
