Very interesting read. I don't do facebook so thanks for sharing.
Gabriella Plants had them a few weeks ago for 12.50.
I bought the one I have back in Dec. From a local greenhouse. I paid $35
I personally have had good luck with pink princess, Florida beauty, and splash Gordon. The princess and beauty do require more care. I have had both of them for about 6 years now. I grow them in bright indirect light with humidity of about 60%. I cut them back if they start to give me to much of one color. If you can find one for a fair price I would give them a try.
