I purchased a small scale from Myweigh (can't remember the model offhand): 100 g capacity, .01 g resolution, less than $100. Quite satisfactory for my current emulsion-making needs.

I would buy from them again, but a unit that can handle at least >200g to accommodate the added mass of a glass beaker etc.,

The specs for scales can be misleading: resolution and accuracy are two different beasts. A scale with .01 gram 'resolution' may not be 'accurate' to 0.01 grams.
