It was less than $25 shipped.
I also have a mechanical beam scale, which I proved the digital scale out with. It passed.
It doesn't drift, and it is absolutely repeatable to +/- .01gr. It is not affected by light or temperature.
The only "idiosyncracy" with it, is that it needs 5 minutes warm up time before it has a stable zero, and it doens't like fresh high quality batteries. It prefers the lowever voltage of cheap crappy chinese batteries. I've had it for 3 years, and I'm only on the 2nd replacement battery set. When it needs them, I take batteries from my TV remote control and use them - and put the NEW batteries into the remote. The other slight issue is the size of the cup, which is about full with ~45gr of Varget in there. I bought a strip of .007" thick brass sheet at the hardware store for $5 and hammer formed a new cup that happily holds (with room to spare) the 95gr of Retumbo I need for my 338LM.
It is absolutely sensitive enough to detect one kernel of extruded rifle powder. I believe a kernel of Varget is between .02 and .03gr, because sometimes the single kernel will bump the reading by .02, and sometimes .04.
I have a 45gr test weight I made from cutting up a coin, and verify the scale before use. As long as its warmed up, that coin will ALWAYS read a stable 45.04gr. ALWAYS! What more could you want - other than made is the USA?
I agree with those that say if you can only have ONE scale, a mechanical beam is the way to go. However, this thing is worth 5 times the price you pay for it. Ebay is loaded with these things.

I have not found any on eBay that are .02gr accurate. What brand is yours? </div></div>
This is the unit I have:

I did a quickie search. I suspect you can find the identical unit cheaper.
