I currently use a Lexar 256M 12x. It works flawlessly (finger crossed - knock on wood) My wife has asked me to look into more memory (she asked me to spend money...hehehehe!) I am torn between an 1G IBM Microdrive and a MindStor 10G. I like the idea of the 1G MD card but I have heard about reliability issues. I also like the MindStor because of its storage size but it is another piece of equipment to carry.
