Ditto what everyone said about the Classic Turret.
I have digital calipers, which work okay, but mechanical is the way I'd go if I could do it over again.
Get the carbide dies. Very much worth the minimal extra cost.
Like the others, I prime off the press.
ProAutoDisk works well for Clays. With H335, enough grains get by to interfere with smooth operation at times. I took some sandpaper and VERY CAREFULLY sanded down the two plastic ridges at the bottom of the powder hopper that come into contact with the aluminum body. There is one on each side. I did equal passes on each side, and I was VERY CAREFUL not to take away too much plastic. I stopped when I could barely slide a single sheet of paper between the powder disk and the bottom of the hopper - you need a little space to keep things from binding. Since then, no problems with H335.
Sometimes, the operating spring for the ProAutoDisk binds. Watch for that.
You can get a tumbler, but I found it less expensive and less hassle to wash brass with the NRA vinegar/dishwashing detergent forumula, with the added benefit of no lead dust issues, tumbler noise, electricity costs, or media costs.
Get a set of check weights for whatever scale you get, and use them. My 5-0-5 RCBS scale works well.
When you move to rifle reloading, you'll need to get a case trimmer. I like the Lee system, but it tends to wear down and go out of spec after a while. However, they're so inexpensive that you can get several for the same price as a more expensive system, so it's best to get two or three at the same time to save shipping costs. Also, forget about the Lee deburring tool. It's junk. Get the Wilson deburring tool. And another item for rifle reloading is a primer pocket uniformer. The one I like best is the K&M.
ETA: For rifle reloading, you'll need some case lube. You can make a bunch of it very inexpensively by mixing 1 part pure lanolin to 4 parts 90% (or more) rubbing alcohol. Also, the same solution that washes brass will also clean off the lanolin. It takes two washings, but that's not a big deal. Wash used brass, lube, resize/decap, wash again, load.
