Anne, I have had very good success with Kingston and Sandisk 4gb cards--not so much with cheaper off-brand units. My recommendation is to put as few files as possible in the root. I have found that not doing this can slow down navigation even if the technical limit has not been reached. To make this easier, I create a "current files" directory off the root where I put all the stuff I'm listening to for quick access. Hope this helps.
