I don't order very often, but go all out when I do.
I'm just repotting because my set up is all semi-hydro, and it is easier to convert all newcomers than to wait and have some in this mix and others in that. Also, a nekkid plant is easier to check for hitchhiking critters. Anyway, from what I've read, dendrobiums like being potted fairly tight, so use your own judgment and that of people more expert than I to decide when you will repot your new guys. I only have a few nobile-types and a Proud Appeal 'Ace'.
Good luck!
