Sorry, I just noticed I could see your location right above your post, but I guess I wasn't looking properly :P.
Wubben has a nice collection but they split their plants quite alot I think, which leaves you with only a couple of pseudobulbs while having a nice grown is nicer. They're more prone to survival if they're bigger aswell :P. I've heard of Claessen's Orchideeën, they're quite a while away from me unfortunatly.
I'll be visiting the NOV-dag with my mother (she's an orchid lover aswell but not as fanatic as me:P) but it really would be fun to meet up if you like! We should be there around midday
