I bought one of these about a year ago:
pcmcia card reader, PC Components, Desktop Laptop Accessories items on eBay.com
They are always selling a SLEW of them on ebay and they ship out of hong kong for free. Price ranges for about 2-7 USDollars.
And then I use 1GB SD cards but I wish I could just get a 2GB to work. I'm wondering if it's the formatting in FAT that's the problem. I might experiment with FAT32 this evening.
But it does work, just cuts you off at 1GB for some reason.
