Here's another option. I met Charley at GNYC Aquarium Society. He lists his plants on aquabid.com under the name lowcoaster. His plants are imported from the far east, and from FL. The best thing is, he is glad to assist via email (if you aren't in NY), and he can order just about anything you like.
I've been very happy with the plants I've gotten from him. Some really awesome and unusual Java fern, annubias, and crypts.
