Hi... New reloader here, having just started a couple weeks before Thanksgiving. I'm now a few hundred rounds in, so I'll offer a brief comment or two here and suggest you take them with massive doses of salt.
1) Get a hold of a good reloading manual (I think Lyman is the best I've seen) and read it carefully. You won't regret it. The manual is the best investment you'll make in your reloading experience... along with reading THR's reloading threads, that is.
2) Think about your goals/purpose in reloading. If you are just trying to load a modest amount of plinking ammo now that you know what a shortage feels like, I can promise you that you can put together the reloading equipment needed to do that safely for < $100. As your desires for either consistency/accuracy or output increase, you need to start thinking in terms of a bigger investment.
3) I bought the least expensive Lee press ($30) and dies (<$20) to reload .223. I use Lee dippers for powder (borrowed a scale to verify weight the first time), Lee's hand priming tool, and hand tools for case prep. They all work, and so you can get started for a reasonable initial layout. That said, I'd strongly advise that you *not* skimp on the quality of the case prep tools if you're reloading something like .223 ... There are a lot of actions you have to perform on the cases (trim, chamfer, deburr, remove a crimp, clean the primer pocket) and it gets old very, very fast. Trust me, it gets very, very old much faster in the event that you have crappy tools.
Above all, go slow. Don't be afraid to double or triple check anything. Safety is more important than speed and accuracy combined.
