I'd second Unclenick's suggestion all around.
I have a RCBS beam balance scale that has to be every day of 30years old, and might be closer to 40. I check it from time to time with my calibration kit, it has never changed.
I bought my RCBS powder measure at the same time, and have charged some unknown number of rifle/handgun/shotgun shells, yep, even shotgun shells with it, using extruded, ball, and flake powders. Still works just fine. I take it a part and clean it every few years, not sure that's necessary.
Powders? Think ball powders. My 7mm Mag shoots the very best with R22, and IMR 7828. Shot lousy with H-1000 and WMR. But most of my rifles and handguns like W-231, W296, BL-C2, & H-414. They are the very best for uniform charges. Flake powders are nearly as good.
Lee Dies are very good, and for the ones I've purchased, every bit as good as the RCBS dies I've accumulated over the years. Get new dies, and clean them from time to time. The dies I purchased when I set up my own bench are still working just fine. I know guys who own dies from different makers, and some have more features than others. I don't think you can find a bad set for any dollar.
