Hi Larry.
After what I know, you don't need a special kind of SD card - just it matches. Find the cheapest. I brought with me the card and looked at a photo store, and bought a 128 Mb card for about $800.00 here in Denmark.
I have two now, but soon I'll have to buy one more or change to a bigger.
Good luck in finding your card.
Musical regards
