Nice choices!
After making a huge mistake by buying Laelia tenebrosa on EBay in a 3" pot, when I could have gotten a 5" pot elsewhere for a few dollars more, I just splurged on a 6' pot of C. dowiana, from Odom's. I think I'll back off the buying for awhile and see if I can grow/bloom what I have.

Not a pretty plant, but hopefully a beautiful bloom
