I use an Acculab VI-400 that I've had for many years. It is accurate to 0.1 grams, which I felt was adequate for my needs. Acculab has gone out of business as of January 2011, acquired by Sartorius Group. Sartorius makes a similar line of reasonably priced accurate scales. The prices seem comparable to the old Acculab line. I can vouch for Acculab, but I haven't used Sartorius scales so I can't say if they are comparable in quality.
