Pictured above is my kitchen scale, an OXO Good Grips Stainless Food Scale. This scale weighs food in 1/8 ounce increments and will weigh food up to eleven pounds. It features a ZERO button, which offsets the weight of the container so that it does not figure into the weight totals. It also has a backlight button that makes the display easy to read in dark conditions. And here's a really nice feature: many times a large bowl will obscure the display, so the display detaches for easier reading.
It's powered by four AAA batteries. I got mine at Amazon.com for $49.99. They also sell a five pound model for $29.89, but that model does not have a backlight.
