Bought an Aussie O-Frame press used, for $50, 40 something years ago and bolted it to a slab of 6x2 hardwood which I G-Clamp to a bench.
Worn out several sets of priming tools and the affixed priming arm is a long ago forgotten memory.
Oil and tightening any leverage points is the key. The most important aspect is whether the die hole was bored straight before tapping.
After reviewing a lot of presses, there are actually some out of plumb.
The other item I like, is a digital caliper which I was given by Keith Herron, the Hornady Distributor in Oz quite some years back.
Although I have and have had all the trickle and thrower devises, I still use the same Tea Spoon and plastic cup I pinched from my mothers kitchen to hand weight every powder charge.
