Best sources of inexpensive orchid seedlings?

[orchidphile]

Hi, everyone. I'm new to the Board and would like to ask a question about sources. Like almost everyone, I started with full sized orchid plants. Since transitioning to semihydro, they've done so well that I've started trying my luck with much younger plants to build a bigger collection at a more affordable price. I've found two very reasonable sources for seedlings: Secret Garden Orchids and Olympic Orchids. I placed an order with Secret Garden, and was very pleased with the size and the health of the plants.

But now I'm wondering if there are more mail order sources with really low prices for healthy seedlings. I have lots of full-size plants, so I don't mind waiting a year or two for the rest.
