I found a reference to this site in another fourm. http://www.mydigitaldiscount.com/products.cfm I can't vouch for their reliability, but you can check them out. $200 for a 10 gig and free shipping I think. The person who posted it was satisfied with the service.
what has stopped me from buying one is I can not seem to locate one that has firewire or usb 2.0 instead of USB 1.1. I mean can you just imagine transferring 20gb of data over USB 1.1? It takes nearly 30 minutes to transfer 1gb of data from my ibm microdrive using a USB 1.1 card reader.
