In orchids as in other things you often get what you pay for...
Ray has very interesting plants. And very low prices. Some of his plants are probably mislabelled (some of mine are too, I suspect). Back when I had space I would always order his monthly special (as listed in the 'Orchids' magazine), which was usually half a dozen or so species or hybrids for something like 60 bucks with shipping. I got a lot of really nice stuff that way. He stopped doing that kind of special a while ago (5 or 6 years maybe?), so I haven't ordered since. Even if I had space.
Once he had a $2 each sale for sufficient quantity, and I got a couple hundred bucks worth. Really nice stuff (and some not as exciting stuff too).
Anyway, long and short of it is that I haven't ordered from him in a while, but I always thought I got what I paid for when I did.
