I've had the Shure for years, and still have it. Haven't used it for years either.
It works, but of course isn't as convenient as many digitals are.
The digital pictured is one of those Camrong scales. I had one, didn;t like it at all, and sent it back. I might have gotten a bad one, was inconsistent with proper reading, and unreliable, so back it went for refund. Was bought from an audio dealer, but probably makes no difference where they come from. Price on them vary from peanuts, to astronomical.
A company like Old Will Knott deals strictly in scales, and carries a myriad of very good scales at cheap prices, and many are not at all toys.
I finally settled on a Clearaudio clone from them, the Proscale LC-50, (weighs to 50 grms down to .01g increments) and it is dead accurate. I also like the fact it uses regular AAA batteries, and not some harder to get, and more expensive camera type batteries.
Downside with a scale like the Proscale LC-50, or those similar, is a weighing platform that is not ideally suitable for just simply setting on the platter. The LC-50 has a platform height of .6" One can do as others have, making a weighing ledge from a credit card, or some non-ferrous metal. Or create some form of stand that the scale can sit next to the platter at platter-record height. That's what I did. Mark
