As for the scale, there's this one for $23: http://dx.com/p/digital-jewellery-scale-10g-2060?item=2 - it's certainly not the best scale you can get but when compared with a $45 scale it seemed the more accurate of the two. If you want to look at other options, head on over to the Scale & Balance Thread and you can find some great suggestions there
