Yes, I have knowledge about all 3.
Jim Roberts is a great guy, good stuff and over the nine years i was in Florida, I made sure to pick something up from him when he was a show vendor or club speaker. I don't know if it will do you any good, or even if he remembers me, but feel free to say that I sent you! It couldn't hurt.
Rafael over at Plantio is another good guy. He has always had some wonderful species including digbyana. I have bought from him often!
Odom I don't know as well but along with Plantio and Jim Roberts, he was a yearly vendor at our annual show in Naples. I never visited his place but he is another nice guy!
I don't think that you can go too far wrong with any of them.
Good luck.
