I am thinking of getting a balance to mix my own chemicals. I was going to get one of the lesser priced Acculabs like they sell at Photographers Formulary bu then I started thinking about mixing up PyroCat which has some ingredients that are .2g and the balances tolerance is .1g - not a good recipe for success. As always the thing complicating this is that I don't want to send a lot of money. Do you have any recomendations on good blanaces for around $300, or less, that are accurate to .01 grams or better. I don't mind used, but I don't know what to look for/ask when buying with e-bay.

I prefer a digital balance since that is what I am used to from college chemistry, but a true balance would be fine if it is accurate enough.
