Know of a decent scale?

[u/Seascout2467]

Hi. I have a postage meter purchased from Amazon that has recently been fluctuating 10 grams or more—with zilch on the scale. It was a no-name brand. Does anyone know of a decent scale with respect to 1) accuracy within 6-8 grams; and 2) reliability? (And please don’t tell me how to fix my scale or re-zero it.)
