I don't know how much you shoot right now. New hand loaders tend to realize they have shot more in the 12 months after they started rolling their own. Shot for shot it is cheaper when only considering the cost of components, especially on once fired brass. After all the brass is free once it's been fired once. But it may take thousands of rounds to recover what has been spent in equipment. I got into loading to produce perfect ammo for my rifles, not to save money. Now that I shoot as much as I do, there is no way I could afford manufactured ammo that would not be as good as my loads tuned to my rifles.
As is the case with many hobbies, you start out simple, and slowly upgrade equipment. As RedChevy wrote, most of us find that we all eventually gravitated to an RCBS Chargemaster. It is just as accurate as many other digital scales yet cuts your loading time, often, in half. For me, that equates to many hours saved at the bench every year. So if you can afford it right now, do it, it'll be cheaper in the long run.
As far as presses, there are lots of good ones. Many are 50+ year old designs still going strong. Another big ticket item for me was a Forster Co-Ax press. I started on a simple single stage, went to a turret press, sold it at a loss once it could not keep up with the long list of varied cartridges I load for, and finally landed on the Co-Ax. I wish I would have started with it in the first place. It would have saved me more hours, and more money.
Quality, accurate calipers are a must. I like analog, but there are good digital ones on the market.
Case trimmer. A chore I hate, but a Forster lathe trimmer will get you going. I'm about to upgrade from that as well. You'll also need a chamfer/ deburring tool. And I also use a flash hole deburring tool on new brass. It's a one time project, but I can see how not doing it would cause me negative results.
