I found these scales on ebay called tomopol. Seems like this is a manufacturer from Poland. I bought one for 15 Euro that weighs up to 80g in 0.01g graduation - the scale I had before only has 0.1g graduation and cost twice as much!
From what I tested (with standardized weights) the tomopol seems pretty accurate, I think.
They also have this 0.001g graduated scale for only 40 Euro. I didn't need that, but it's a pretty good price.
*edit* I just saw the scale from China is only 25USD for 0.001g graduation. Now that is an even better price! you don't even have to fear customs charges because 30USD is free from China.
... and I really don't think a chinese salesman would ever ask questions. Last time SWIM ordered a 60USD CPL Filter from China, the shop put it in the package including a receipt over 60USD, and on the outside they labelled it "gift, value 30USD" so that SWIM didn't have to pay customs fees. SWIM wouldn't have dared to ask them to do that... they just do it because they can maintain lower prices like that (i.e. on said Japanese made optical filter that costs like 150 Euro where I live)
