There are a number of people selling crystal reds over in the "Swap n Shop" forum on plantedtank.net, though you have to have an account to see that forum at all. I personally bought a batch from greenisgood and was pretty happy with both the quality and the care taken with packing/shipping. It takes some patience and luck to get on her waitlist, though, since it fills up quickly.
I've heard good things about most of the regular sellers over there, as well.
