I've seen it on Hardy Orchids in the past as well... just too scared to try it because it's not cheep and I've never grown Cyps. Hardy Orchids only ship Cyps between September and March so I may try and pluck up the courage later in the year.
C. calceolus is probably not the best starter Cyp. I would start with parviflorum (which is what's on the OB logo), reginae, or one of the hybrids. Just a thought!
