I use a digital postal scale and love it. I'm sure either one of the scales you have pictured would work fine.
make sure you get one with a tare feature, where you can put your mixing bowl on it and then zero it out. also its handy to have one that weighs, lbs, oz, grams kilos etc.
I use the first one you have pictured and love it
I love my Salter too, but it's one that is mounted on the wall. You flip down the base when you need to weigh something. It is so handy, I use it almost everyday.
I personally am a big fan of Soehlne scales. For years I used this one Soehlne Future Scale but then recently upgraded to a newer model, this one Soehnle Triple Digital Food Scale.
Both are amazing scales, have an 11 pound capacity, switch between grams/kilograms and ounces/pounds, and of course have a tare function. I use mine nearly every day.
Thank you so much for the replies......I wasn't notified!
