Roland D-50 Sound Cards

This past week, I had my Roland D-50 organ sound card, a "Screamin B3" made by Valhalla, stolen from my music store. I can't tell you how bummed I am!!It had 64 Patches, all original, and now I have NO replacement!!!

Does anyone have a resource for locating a card of this type? I relied so much on it for live gigs, and now I don't know what to do.

Any help would be greatly appreciated.

Good Afternoon:
I apologize because this isn't really a reply to your request but rather a request to you. I am trying to find a used D-50 and was wondering if you could share some opinions on the unit before I buy it? I can't seem to find much on it. Can you download additional sounds? Or buy them? How are the piano and organ sounds and the built in voices in general? What are the synth voices like? How is the touch on the keys?
Thanks for your time and good luck in your quest
