The RCBS 5-0-5 is pretty much the gold standard of affordable quality balance beams. I started with a Lee safety scale and quickly figured out its quirks and how to get it to read accurately with consistency. It actually is a very accurate scale but suffers very finicky operation. You get what you pay for, but if you know how to use it you do get accuracy. Upgrading a couple years later to the 5-0-5 was a very pleasant experience. It still retains excellent, repeatable accuracy but with much smoother and simpler operation. And over 5X the weight capacity. Setup, zeroing and adjusting is faster and easier but my favourite part is the approach to weight. The Lee has a very narrow weight range between where the beam starts to lift and your target weight. Its easy to blow right past and have to remove powder from the pan. The RCBS has a much wider range and smoother operation. Its now my #1 trusted scale. I've added and RCBS Chargemaster lite for loads that don't need tenth grain accuracy. At first it was a little inconsistent, varying .1 and almost .2 on rare occasions as compared on the 5-0-5. RCBS recommends a break in time and after a couple hundred drops it has settled in. My last batch was 50 rds of 9 gr red dot for .30-30 and none measured a full tenth off. Between the 5-0-5 for precision loads and the CM lite for higher production stuff I'm quite happy. Neither can do what an FX-120i can do, and I envy those with auto tricklers set up on theirs, but for my budget this combo kicks ass.
auto trickler can still be "on budget" if you are moderately handy.
My home made diy auto trickler cost less than 25 bucks and a bit of time to put together.
