I use a Midway Quick Draw electronic scale, and it has worked well. Midway puts them on sale once in a while. I would look for a scale with 0.1 grain resolution in the range you mention. I would add that a fan will still give you problems. A scale, whether balance beam or electronic, is designed to respond to a mass (force?) on the pan. A breeze will exert a force and result in a reading. I turn off the ceiling fan while I am reloading and using the scale. Depending upon how many rounds you are loading, you may want to consider a powder measure. Once you calibrate the measure for a given amount of a given powder, you only use the scale as a confirmation that the volume of the powder measure has not changed, about once each 20 to 30 rounds. My powder measure is also a Midway, and it seems to work well. A powder measure in combination with your balance beam may be a viable alternative to a new scale; however, I'll have to admit that I bought my electronic scale before I bought my powder measure. Sorry for rambling.
