Especially if you like Americanos, chances are you'll be happier with filter coffee from good beans, rather than spending it in an espresso machine.
Get an Aeropress, or Hario Switch, or Clever dripper. A kettle and some filters. For beans buy from roasters that do light/meduim roasts, and print a recent roasting date on the package/website. The only expensive item should be a grinder, look at 1zpresso Q/Air/X or Kingrinder K6 if you want to limit price.
Not gonna lie, this sounds like way too much work.
What I am mostly looking for is some sort of an easy access to a diluted coffee like the Americano, really. I am OK with buying 1-2kg of beans because I am fairly sure that's going to last me 3-6 months. Cleaning the machine I've done in offices -- 3 minute job.
But any more commitment just sounds tiring. I am not a coffee connoisseur by any stretch of the imagination. But light caffeine doses absolutely do help me in very measurable ways. I need easy access to that.
Buying a coffee machine is not a big commitment obviously, I am just afraid I'll deem the experiment unsuccessful in a month and then I'll have a nice machine lying around doing nothing that I can't easily sell.

This style, pour over machine that grinds itself, but uses all water you put in, so it's not fully automatic.
It's automatic enough, but also very cheap. Maybe even ⅒ of a price of a fancy espresso machine. And you can add "too much" water (than the setting you set) to make lighter coffee.
You can get an over-the-cup pour over for ~$10-20, basic blade grinder for the same, and a pack of filters. That’s all you really need.
