Just my 2 cents worth on the re-pot for the lovely Laelia, Carol. Since Ursula suggested it, I'd vote for the clay pot option.
I've tried just about every type of pot and mount in the last few years, and for this humid climate of ours, most of my orchids like the cedar baskets. But I use a clay pot for plants that like more moisture, or cooler temperatures because not only does the clay 'breathe' it also cools the roots a bit as the water evaporates through it. All my Cymbidiums are in clay pots now, and they really seem to be doing better this summer than last. They're under the roof overhang so they don't get rained on, but I spray the pots to keep them cool. Same with the Phals.
For you, where you have the nasty dry heat in the spring and fall, I'd think the clay might help keep up the humidity for the plant as well as keeping its roots cool.
