I started with a Lee Loader in 1968 and upgraded after I got out of the military in 1973, I bought a Rockchucker press and it is the only press I have today and its still going strong.
At times I thought about a progressive press, but in my opinion you will get the best accuracy with a single stage press. And if you need that much ammo then stay up late reloading and call in sick before you go to bed.
Learn and read on how to setup your dies to reduce runout. More reloaded ammunition is loaded with excess runout for the simple reason the decapping stem is locked down off center than any other reason.
What I'm getting at is you don't need the best and most expensive reloading equipment, and just know how to get the most from what you have. Meaning spending more won't increase your accuracy if you don't know how to set up your dies.
Below is a Forster full length resizing die, look at the location of the expander button on the spindle, the expander button enters the neck of the case while the case neck is still inside the neck of the die. The spindle lock nut has a rubber washer under it and this allows the spindle/expander button to "float" and self center.
You can move any make/brand die spindle upward and copy the Forster design. Lee lock rings which you can buy have rubber o-rings on the bottom and will allow the die to float and self center in the press when just finger tight.
And if you use Redding competition shell holders the shell holder will always make hard contact with the bottom of the die.(press camover) This removes any slop or alignment errors the press may have in the sizing operation.
No matter what you read, full length resizing with a standard factory rifle will give you the best accuracy.
Below is a full length resized cartridge in a rifles chamber, the base of the case is supported by the bolt face and by the bullet in the chambers throat. The cartidge case walls and neck do not contact the chamber walls, meaning full length resizing eliminates any case misalignment problems with the bore. This in turn lessons the effects of neck runout and improves "YOUR" reloaded ammo.
Bottom line, my old Rockchucker press is still going strong and with a few simple tricks to reduce runout and spending less money I'm still in the game and haven't spent a fortune on reloading equipment by reading about what really counts.
These two web sights below have a wealth of information on reloading. But just remember these websites are geared toward custom rifle and much of what the do tweaking their brass has very little effect a stock factory and factory size chambers. As an example you would be nuts to neck turn brass for a Winchester 30-30 rifle but the tips you read below will help you make better ammunition.

NOTE: you will find the rubber o-ring tricks at both websites, and at the Riflemans journal you will find a humorous quote by the late competitive shooter Jim Hall of Sierra bullets who always full length resized his cases.
"I get the best accuracy when my cases fit the chamber like a rat turd in a violin case"
My favorite saying below.
"All the information in the world is written in books and all you have to do is read".
And after over 47 years of reloading the biggest problem new reloaders have is not reading the front part of their reloading manuals and absorbing all the information.
