unless you have a lot of money, or know exactly what you want, start with a lee single stage kit then upgrade as you go.
You will always need a cheap single stage for various things anyway so it's never lost. I still use mine for priming, sizing cast bullets, etc...
You cant figure it all out before you start anyway.
As you go, your needs will become more apparent, and you will see what you like or dislike, and then see where you want to spend money or not for better quality.
I still use some lee stuff, but I have upgraded a lot of components.
Seriously, for the price that it costs to just start with a lee kit, just do it, start with the kit and lee dies, and then see what more you need down the road...
I have been reloading for 7 years and still buy gear every year and upgrade as I go.
One suggestion, though, if you buy a progressive press eventually, just get a dillon. The lee loadmaster is not worth it IMO. I should have just bought a 550 instead.
Now I have a 650 also, but it's not really the best press for low volume multiple calibers. (I only load 9mm, 223 and 308 now though, I want to keep it simple and I have sold all other guns....).
Reloading 50 different calibers is not for me.
FYI, I now have a xl650, co-ax, loadmaster and lee breech lock single stage.
I now have a mix of forster, redding, dillon and lee dies. They all work. It depends what you want/need.
I mostly use the coax with redding and forster dies for precision rifle.
Mostly use the 650 for bulk 223/9mm
Mostly use the loadmaster for small batches of test 9mm because I don't want to mess with my properly adjusted 9mm FMJ toolhead.
Eventually, I might just remove the loadmaster from the bench and get another toolhead for the 650 to load cast bullets with their respective settings.
(I hate adjusting dies, I would rather do it once and then never touch it again).
You will eventually add case prep tools, case cleaning tools, measurement tools, better scale, etc, etc....
I am also somewhat into bullet casting for pistol, so that's more casting gear, sizing gear, lubing.... powdercoat gear, ...
