Hi Susie,
I can't recommend a specific brand. But, I have found that I really like the one's where you can put any container on (before weighing the food) and then reset to zero. That way, for example, you can place your dinner plate on the scale...reset to zero...and then weigh your meat directly on your plate. Saves time and dishes!
I've used digital scales from Wal-Mart, Target, Weight Watchers, and Williams Sonoma (everyone in may family has a digital food scale). I haven't been able to tell a significant difference--except in how long they last.
Hope that helps. Happy shopping!
