beam scales work just fine (I don't own one), and most of the rest of the equipment list if spot on. I like the K&M, as it's one of the top two out there (Sinclair is the other one). In the mean time the OP can get by with the one on the Forster press. It's simply the best press mounted priming device, but still nothing like the K&M. For a case trimmer, I like the Wilson or the Sinclair (made by Wilson). Lots of options, and cuts the case lip extremely square to the center line.
A lot of folks will tell you to buy a pair of digital or dial calipers. Work very well for outside measurements, but not so great when measuring a bore diameter. I use a set of small hole gauges to make the measurements. A good pair of one inch micrometers is a must. Don't buy the Chinese stuff in measuring devices! You get what you pay for here.
Now it's common knowledge around here that I like the NECO gauge. Not perfect, but about as good as you can buy off the shelf. I use nothing but wand type indicators due to their accuracy alone. Forget those long travel indicators. You don't need a .0001" indicator, but a .0005" is about right. Yet I know a couple fellows that are well known in the shooting and reloading world, that use .001" indicators!
