always a good question to think of is how many people in the US want a sanderianum (or multi hybrid) or a hangianum or a gigantifolium or a kovachii of whatever. Probably tops out at a couple hundred, maybe a thousand tops. Probably most of those people at this point have one or several sanderianums and are now not interested in buying more of them. The market, and particularly the hobbyist market, is relatively saturated with these plants. A good demonstration of this is that you can own an awarded sandy - recently awarded sandy - for $400 (on Zephyrus Orchids' site, from their beautiful AQ), which is a tiny sum considering the original price of sanderianums 8-10 years ago.
I think that in paphs, if you're going to be selling commercially, you have to grow things up to flower as quickly as possible, and you have to find a market for unloading the junk you bloom out. There is always a market for good stuff, but unloading the junk is the challenge. In the US only in hawaii and in florida is the production cost of seedlings low enough to sell for less than your $40.
