I searched and found quite a few scales but I did keep seeing this one scale advertised called the GEM-7. It is the most accurate out of them all, according to its specs. It measures as down to 5 mgs. And it happens to be innexpensive ranging from $16 to $23.50. So I ordered one (for $16 if course) from nastyglass.com. I'll let you know how well it works.
