I have had a lot of equipment in my loading room. I wish I would not have spent sooooo much money on things that didn't work. I wish I would have purchased right the first time so I didn't have to do it over. There are ways to do it economically when you get started so you don't have a big cash outflow up front, but then you need to get quality equipment.
I purchased the Lee priming tool probably 30 years ago. I still have it and it works great. It is sitting beside it's partner. I have two, one for large and one for small primers.
My first press was/is an RCBS single stage. It is still set up in my reloading room and is still used very often. It was well worth the $60 I paid for it and the items it came with.
I bought a red progressive press and ended up getting rid of it after a few years of use. It never ever worked right, but I did get it to load. I now have two blue progressive presses on the bench and another on the way. They have been well worth the price. (Dillon)
I tried a couple brands of cheaper dies. They seemed to work good, until I got into tailoring hunting loads and shooting competition. I soon found out my $35 die sets were so much better than the $19 ones. Most of my dies now come out of boxes that could be any one of several shades of green. (RCBS/Redding)
I have had several different kinds and types of powder measures. My original Lyman is the best. The Lyman little dandy worked great when I first started loading pistol ammo. You just changed the bushing to change powder charges. Hop it from one empty brass in the tray to the next and you could charge 50 cases in the matter of a minute or two. My new Lyman electric trickler was too long in coming. I should have purchased one of these years ago for extruded powders. Well worth the $219 I paid.
I started deburring case mouths and primer flash holes with hand tools. Still have those tools and still use them sometimes. A buddy of mine told me about this new (at that time 30 years ago) electric pencil sharpener from radio shack. Used 2 C cell batteries. You could take out the cutter, cut off the base, and it fit perfect in a 20 guage shot shell primer pocket. Cut off the shell about half way down and that big fat deburring tool fit perfect. Wow, electric deburring tool! Just push down on the deburring tool and it came on. zzzzzz and you were done. Then along came the RCBS Trimmate. Wow, all of those hand tools screw right on. No more batteries. Plug it in and go.
I still have the RCBS trimmer I borrowed from Dad about 15 years ago (he has never asked for it back...hmmmm). I wore out two of the gizmo I purchased to run it with electric screwdrivers and drills. Still works good by hand if only loading 20 or 50 rounds. Found this great Lyman electric trimmer on a thing called EBay. Wow, new cutting head and it works great. Can do several hundred brass an hour. Well worth the price. Also have a few trimmers made by Lee. Another great idea that works. (Too bad most of the others don't.)
I have two tumbers to clean the brass. One Lyman, and one from Midway. I have put on the larger Lyman bowl and change the media periodically. They have worked great. I just wish I would have purchased that Midway brass/media seperator a few years sooner. Sure saves a lot of time getting the brass out of the media or the media out of the brass.
I have a desk light over the press I am working with. I have it set so the light shines down in the cases. Works great to check powder level on some cases.
I load in a room by myself and have a set pattern. I never prime before I am ready to load. I never leave a charged case sitting without seating the bullet. I always make sure I have completely loaded all I have started and dump the unused powder back into the correct can. Then put the can away.
There is so much more.....
