RCBS powder pro reloading scale

[Shrike]

Someone offered me a 5 year old electronic RCBS powder pro in excellent condition for $100.-
Since there are so many cheap crappy powder scales out on the market that drift their readings and are inconsistent, I wonder if any of you have a direct experience with this particular model?
I appreciate your input.

Unless you have conditioned power supply, zero drafts, no furnace outlets, no static and stable temp, ALL no lab grade electronic scales drift. Two scales exactly the same will show different drift sitting side by side. If you are buying your first scale, stick to a quality balance beam. Everyone I know either has a balance beam to check their electronic scale or uses the check weight every 20 charges or so to make sure they stay properly zeroed. I only use inexpensive electronic scales for brass sorting and non critical weight functions.
