Hi Ken,
Right. I don't get that many at a time. Also, I learned my lesson on re-potting from vendors. I don't re-pot from Marilyn, SVO, Birds, or Marble Branch. Their mixes are already way better than mine and the plants are pristine. I wait until the orchid outgrows their pots.
I do dunk for bugs just in case and now I do a foliar fungicide. So far I've never had an issue with any of their plants. They have become my preferred vendors. Everyone else I re-pot and check for plant health.
