Please post Alibaba link and I need a good laugh.

The OHaus branded one offered here is also made in China: it says that on the back. Those offered by reloading outlets with their own brand are the same products, with a different label. I have inspected scores of Chinese factories, and they are all focused on selling volume. If you think they separate "top quality" from their main product, when electronics is involved, then you need to visit them to verify that because I have never seen it. They all use the same sensor, same method of making the pcb, same method of test, same QA. The total cost of the electronics is under USD $70 and housing is under $20, hence they can sell at these prices in volume.
If for any reason you don't like the style of that one I show in the photo, or want a different range, then
https://www.aliexpress.com/w/wholesale-precision-scales-0.1mg.html?spm=a2g0o.home.search.0 has a hundred others below your asking price.
I refer to Chinese scales here. I have never seen one that is comparable with the FX-i120 used with automated reloading scales that is made in Japan, and has a USP of a very fast response time. The scale offered here is a slow response time scale, that is identical to those listed on Aliexpress. Slower response allows use of a lower grade sensor, and the electronics averages the output to get a better reading. Accuracy improves as the square root of the number of samples taken.
Finally, electronics does wear out with age. The PROMs that hold the program do it by holding a few electrons on an insulating gate of a MOSFET, millions of times over. That charge leaks away with time, so the thing eventually loses its memory, i.e. program, even if it is never switched on. Also the electrolytic capacitors dry out, rendering the power supply useless. Then if left switched on then there are a dozen different mechanisms that cause the micro-circuitry to be eroded.
The bottom line is asking a lot for old electronics, is an unintended scam. Realism gives an honest sale and honest buy.
With all respect Nocrimp, 2nd hand electronics ten years on is rarely worth more than 5% of the original article and you should not be surprised.
