You didn't mention a time frame, but this can be a time consuming process. Amassing all the bits you need to reload, then developing a load that shoots well in your rifle is quite the task in a short time.
The trouble with used gear is that what you want/need may not be for sale when you want it. I'd suggest you look at buying a kit, then filling in the missing pieces.
Plan on spending $700-$1k if you're buying everything new, it can be done for less but IMO you're cutting corners you may wish you hadn't later.
I have a mixture of brands depending on what I liked or disliked about each particular item. Each individual will have their personal preference.
I bought a mixture of new and used, plus I made a few items where possible. Metallic reloading isn't rocket science if I can do it successfully.
I'd suggest finding a local mentor you trust to walk you through the process hands-on, it'll clarify at least some things. A couple of good reloading manuals should be the first thing you buy. They'll explain the basics, the refinements will come with time.
You need, at a bare minimum: press, dies, case trimmer, deburring tools, dial or digital caliper, case lube, case brush, powder funnel, primer pocket brush, trickler, and scale.
I didn't mention a priming tool or a powder measure, or a tumbler for cleaning cases. I prime on the press, rough measure powder with the Lee powder dippers and top up by trickling, and hand clean cases with steel wool or fine ScotchBrite and brass polish.
Add ons are case gauges, primer pocket uniformer and flash hole deburring tool, chronograph, bullet puller, the list is endless.
Once you have all the bits and pieces, reloading is a rewarding hobby, plus you can produce better ammo than you can buy, that's custom tailored to your rifle.
