Personally, I do not think the words "CHEAP" and "RELOADING" belong in the same sentence...
Not only do you get what you pay for, but when dealing with potentially DEADLY ingredients it is always best to be as accurate as possible. There is a big difference between 3 grains of a powder and say 3.2 grains of the same powder.
Any scale that you decide on should be able to measure accurately down to 0.01 or 0.02 grains..
This is what I recently purchased... It works well and i feel comfortable with it level of accuracy. Also it is a good idea to pick up a set of calibration weights to check your scale from time to time..
