I sometimes shoot tethered to my laptop on some types of shoots and so having the USB cord is pretty important to me. Mine are cheap, maybe $10-15 for the cord versus maybe $30-40 for the good reader that will read every card you may not ever have. I'm sure you can find a dumbed down version that only reads a couple of cards. In my opinion should you buy the reader, get one with less slots as that means less things have a chance of going wrong plus it will cost less. And I would just stick to researching name brand stuff like Sandisk, Lexar, Hoodman, Belkin instead of generic stuff that has not the history or warranty.
