Milligram scales/balances, any info?

Hey guys,
Since I can smell some "home-brewers" in our midst (Yes thats you Yohimbe ) I thought I'd ask this here...
How do you weigh small amounts, for instance if you want to weigh 100mg or 200mg caffeine?

Quotes for balances capable of being accurate to the nearest 5/10 mg are priced around R2000.

I considered gunpowder scales, although they might be ineffecient and a chore to use, they are accurate to 6.47mg (1 Grain), cheap and easy to find.

Any other ideas on how to weigh TINY amounts? (Or cheaper scales?)

What you talking about Willis?

Thanks Yohimbe, your advise let me to the keyword "Pocket scale"
There are quite a few available at decent prices with 0.01g accuracy
Will let you know what I get

I know a couple of UG labs use microgram scales accurate to 0.001mg. But as you can imagine those are pretty expensive, especially if you need one with a high load capacity.
