I ~highly~ recommend the Kodak grey cards over all others. Read the instructions. Properly using a grey card is not always as simple as just taking a meter reading off the card and translating it to the camera. There's also the issue of whether a true middle grey is 18% reflectance or 13% reflectance. I believe that Kodak suggests 13% reflectance ... but don't quote me ;-)) For best results - i.e., for critical work, calibrate the card to the meter and then calibrate the processing.
One very nice feature of the Kodak package is that it includes one or two 4x5 cards, a perfect size for carrying about in a photo bag or even in your pocket. There's also a little plastic pouch for the smaller cards which protects them from dirt and abrasion. The cards are made very well compared to other cards I've seen, and the grey tone is remarkably consistent from batch to batch. I've seen other grey cards with the grey tones all over the place.
