If you bought the machine new, have you checked with your dealer? I have the SanDisk Compact Flash PC Card Adapter, I was told they could be found at Radio Shack, Best Buy, etc., and then I transfer the designs to a San Disk Compact Flash, it's around 1 3/4 by 1 1/2 card. I have several sizes but usually use the 64 mb disk. Hope this helps.
