Following on from Ingse's post, I think there's a fair few vendors in Europe have them. I got mine from
Home - Phalaenopsis and More He's a lovely bloke (he comes to my orchid society...) and currently has ordinary and alba (but is sold out of c1). In fact I believe the ilustrating plant for the ordinary is actually my plant... it had two flowers when I got it at Christmas and recently produced another, but I think it could do with being somewhere lighter to give me more! All white so far, but produced in cold weather, so can't wait for it to bloom in the warm!
(I also have the out of flower ordinary manii pictured on his site! Still has the distinctive broken leaf, but flowered very nicely for me since it was taken)
