Heather,
This may be a bit of a stretch, but I once bought an insigne from a place up in WA. Plant was about 8 growths, in good shape, and it cost $20. It wasn't a division, and the parents were nothing to get excited about... "Select" x self or something of that nature.
The place is called "Out on a Limb Orchids". I doubt that they have anything listed on their website (dont know if they have a website), but it might be worth contacting them. The owner is a lugubrious gentleman who seems to have lost the thrill of orchid growing, except for Miltonias. Or maybe he has SAD. Anyway, might be worth a try.
