Thanks all, I ordered the 512MB San Disk CF. There are Type I, II, & III, the differences are thickness and voltage. I used to be able to tell you what was what. I know Type III are rather thick by CF standards and include some of the very micro drives, very tiny hard drives. I think Type 1 are 3.3 volts and II 5, but someone can correct me on that.
