My dad's stuff was all almost all RCBS (with a smattering of Herters and Lyman and a lone Forster trimmer) when I started loading in the late '60s, so that's what I knew when I started to acquire my own kit.
I went through a 'turret-press phase' with a Lyman and a Redding (both long gone and neither missed), I wish I still had my Dillon 550B.
I love my Bonanza/Forster Co-Ax press, it's the single-station press that I should have bought first.
I've never regretted a single piece of Lee gear that I've bought. And I've had a bunch. That's not to say that I've never busted a piece of Lee gear, I have. But I've busted RCBS, Dillon and Hornady gear too. (I'm pretty "ham-handed").
I've never had a bad set of dies, Hornady, Dillon, Lyman, RCBS, Herters, and Lee, never had a problem that I didn't cause.
- I am eternally grateful to Lee for driving down the cost of Carbide pistol dies! My first set of carbide dies were a set of RCBS dies for 9mmP, and in about 1977 cost me around $80! (When a litre of gas was around 35¢ and a job that paid $10/hr was a darn good job)
Scales - I think a beam-type balance is darn hard to beat for precision, accuracy and durability. A balance measure mass, a digital scale measures weight. I have a digital scale, and I have plans to buy a better one; but I'll never give-up my balances. They are too valuable for backing-up the digital scales. I do love the speed of those digitals! They make the sorting of bullets and cases something that one can do without setting aside _hours_ of time.
My father's scale (from the early '60s) was a Lyman Ohaus M-5, which was still going strong when it was lost in a fire in 1994. Was replaced with an RCBS 5-0-5.
I think any quality beam-balance would do just fine (and the Lee balance is great, very accurate and precise; but kind of finicky to use and I wonder about long term durability)
