Finally, some mainstream press about how useful kitchen scales are!  Thanks for the WSJ link, Carol.  I posted about his very issue here last April.  And, as I've just gotten back the copyedited manuscript  of my next cookbook, due out next April Lee Gomes's story is enormously heartening (you need a scale to take full advantage of my book). I truly believe the average American home cook is ready for the scale (the one I use is at the bottom of this page, but the major brands all work fine–just make sure they have a "tare," or zeroing, button and that they can measure both grams and ounces; I also like them to be able to handle up to five pounds).  There's a video on the WSJ link which shows one reason they can be so useful and also how scales actually work.
