You beat me to it, I was planning on updating everyone today
I've had responces back from Oak Hill, Parkside and Hausermans.
It looks like there is good supply of...
Paph delenatii
Gastrochilus japonicus
Doritis pulcherrima
There is lower supply, possibly enough for a split project of the following...
Aerangis fatuosa
Paph concolor
Angreacum didieri
I am tempted to put these 6 into the poll (subject to a final check I'm just making of some prices from Parkside) and if one of the more limited ones wins then split the project into two with the second place one as well. What does everyone think?
