Query: What retailers won't tell you.....

What the retailers won't tell you is that card speed matters if you want more performance out of your digital camera. Most will try and sell you what they have on hand. If your an avid photographer, spend a little more on your CF card to get a little more, you'll be much happier. Point and shoots will be happy with the cheaper models.Research pointed to LEXAR as the leader in CF technology. Good luck and happy picture taking.
