Hi Ken,
I think Jeff at Fish World in Blue Springs (MO side) might be able to get some from ORA. Tell him I sent you.

I used to breed them - getting a M/F pair is the tricky part, but once you get a set, they should breed. (They aren't like clowns - females are rather promiscuious, and will breed with any male they can convince, I firmly believe.)
Look for a couple that hang out together in a tank.
Oh, and FWIW, I don't know that there's a huge difference in TR vs WC. If you are planning to breed them, you might actually look for a WC pair, as there will be less genetic inbreeding... although they are pretty inbred to begin with.
HTH,
Danielle
