Persimmon?

So this is less an informative post and more a post looking for information. I've been looking for a certain variety of persimmon as stock for some time now. Diospyros rhombifolia, or Princess Persimmon. These have very tiny fruit, about an inch across, and I've been wanting to get my hands on one, even just a very small (read: twenty year project) piece of stock to try. If anyone knows someplace on Long Island that sells them, or a reputable online dealer (Brent at Evergreen Gardens had them, but he's sold out :( ), please, let me know!
