I don't think that a budget of $200 to $400 is unreasonably low to get started, and I don't think you're full of anything. I started loading two years ago this month.
My startup equipment costs (not counting components):
Hornady LnL Classic single stage kit, $200 (clearance item) plus $20 shipped, no tax.
RCBS dies in 45acp caliber, about $60 after tax (bought at store).
RCBS shellholder in 45acp caliper, lets say $10 after tax (also bought at store).
I already had a set of calipers, but lets add $30 for a cheap set.
So my cost to start was $290 (or $320 if you include buying calipers), and my equipment was all new. I lucked into a clearance deal on the press kit, but the above cost was everything I needed to start loading except for a tumbler and components. So it can be done on a budget if one is patient and shops around. And this was Hornady and RCBS stuff, one can most certainly get Lee or maybe Lyman stuff for less which would do the same job IMO, and should give the same results once the user learns the equipment.
I have since added equipment that I felt I needed or wanted over the last two years, and my equipment cost is still under $1000. Five die sets, four powder measures, a quality beam scale, tumbler, some VERY nice aluminum funnels, etc....
I consider it a hobby, and enjoy it, so I don't mind spending a bit of money here and there. But when I started I wanted to spend as little as possible in case I didn't like it. After buying components, my first loaded round cost about $400~$450. But the next 999 were free, LOL!
To the OP, if you really want to do it, then do it. Shop around until you find what YOU want at a price YOU are willing to pay. New or used, it's out there. Be patient and be ready to grab it when it comes available. And above all, be safe when you start loading!
