This is pretty accurate. The very cheapest option is an aeropress and manual grinder but that's so much goddamn work it's really not worth it compared to just doing a pour over or something.

If you're patient I think you could get a pretty good single boiler and Burr grinder setup for under $500 used. But that's still a good chunk of change, the kind of thing that only makes sense if you're constantly buying espresso on the way to work (at-home price of two shots is like $0.69 vs $4 at a shop) or if coffee is your main hobby for years or something.

Last year I thought, "hey, I should get one of those manual Italian-style lever ones, I bet they're cheap since it's just a big lever and shit" nope they're more expensive than good single boiler systems wtf.

I'm sticking to my cloth filter in pour over into a big steel measuring cup method, lol. Total cost of like $20 and makes great coffee.
