FWIW, I have upwards of five card readers. Two FW400 CF readers, two USB umpteen-in-one card readers, and one USB SD card reader (so I can read sodding SDHC cards.) I've purchased two others; one I gave to mum, and one I think my old housemate nicked when he moved out. When I get a new Mac desktop, I'll probably get an FW800 CF reader as well.
