Lets not dazzle and confuse this person with all the electronic fandango crap.... He don't need it now. He needs basic tools.
You have a single stage press, get yourself an RCBS or Lee hand primer. Simple effective and cheap. The Lee shellholder set (you need that) fits both plus it fits your press and it's cheap. You can upgrade to an auto prime later and sell your hand primer but I doubt you will. I prefer my hand prime over a press prime anytime.
A loading block made from a 2x4 with proper size holes works to hold cases. Been using 2x4's for years for loading blocks. Cheap again.
Both Lee and RCBS make a basic case prep kit with hand brushes (but nylon bore brushes of the correct diameter work too. Get a chamfering tool for case mouths and neck chamfer.
A powder funnel and trickler and a beam scale, not the electronic crap yet. Nothing beats the accuracy of a jeweled movement, magnetically dampened beam scale, nothing. I use a beam scale even today. I have an old but accurate 5-0-5 RCBS. Inexpensive., lasts forever.
I have a hand trickler, a Lyman, works fine, was cheap.
I use an RCBS powder measure but they are all good, just learn to move the charge lever the same speed and slap the upper and lower stop everythime. No biggie. Cheap again. Forget the micrometer whatyoucallit for the powder measure, useless. Put your micrometer head on your seater die....
A set of dial calipers to measure COAL and neck concentricity should do it. Harbor Freight has some cheap but serviceable ones that if you drop them, you won't have a coronary....
I like al dies, Lee the least, Redding the most but dies have to do with personal preference and caliber being loaded so I won't go there....
That will get you started, if you can get components today.... Thats another challenge.
