Actually, a few years ago I started looking at some of these espresso machines and yeah... they can get a bit expensive. I figured i drink enough coffee to need a high end espresso machine. Fortunately/unfortunately, I was distracted by some other hobby. If I remember correctly, that's when I got into rock climbing.Oh, there are significantly more expensive hobbies out there, but in context a lot of people may think hundreds or even thousands of dollars on coffee brewing is insanity.
Still, you can sink a lot into it. Next year I plan on upgrading my espresso machine from my entry level machine to one that's got more bells and whistles than anyone could ever need and a price tag that made my wife's eyes roll so hard I'm pretty sure they did a 360 in her head.
For a while, though, I got deep into the coffee brewing videos on YouTube. Started watching a lot by this guy, Jeff Hoffman. Found his videos oddly relaxing.
