Steve, There seems to be a new kind of card almost monthly. If you go to http://www.imaging-resource.com/search/accessories/flash_card_readers/index.html, you can read about some of the readers. Both Imaging Resource and DPReview are good sources for camera and accessory information. Also, you might check the site of Eric <http://www.drbott.com>, our host for this group, to see what Dr. Bott has to offer. Might as well be a little payback. Harry M. Kachline
