Coffee

I would steer clear of the Hario Mini Mill. The ceramic burrs are horrible for consistency and, as others have said, it's terribly arduous to grind beans with. I think the low price point leads a lot of people to purchasing it and then giving up on manual grinders entirely because the experience is so frustrating.

The Capresso is a step up from a blade grinder, but it's not going to be capable of making a good shot of espresso consistently. That isn't to say you won't get a good result occasionally, but it gives you far less ability to make minute adjustments to grind size.

1Zpresso does make fantastic grinders at multiple price points, so I'd second any recommendations that you get for them. The J series grinders are certainly capable of making a nice drip coffee, but are definitely the more espresso-focused grinders of their lineup. If your priority in a coffee is body over clarity, it's right up your alley. If it's the opposite, then you're going to want one of the K Ultra. The only real difference between the JX and the JX Pro is the grind adjustment mechanism, and I'm not too inclined to say that it matters, especially if you don't have a great espresso set up. The additional steps only really matter in the espresso range, and usually there are many, many more tweaks available to you when dialing in a shot. If cost isn't an issue, I'd still suggest the JX Pro, but the difference between the two is usually not going to be the thing that makes or breaks a shot.

If you get the higher tier 1Zpresso models or a Commandante, just know that you're well past the point of diminishing returns when it comes to grinders. Secondhand manual grinders are perfectly fine. My first 1ZPresso (the JX) is going on near a decade now, and it's still more than capable of brewing something delicious, though admittedly it's become relegated to a travel grinder.

If you really like the idea of an electric grinder and have the countertop space, scour used markets for a Mazzer Super Jolly. It's a pretty standard cafe grinder, and exists under a couple different white label names. I've seen them around me for about $250 USD or less, and they're pretty sturdy. The burrs are easy enough to change if they've been worn down by the cafe, and they usually run around $50 USD. It's not a more capable grinder than the 1Zpresso or Commandantes, but it's still better than the other electric options in the price range if you're not enthused about manual grinding.

As far as espresso machines go, I'd strongly suggest looking at the used market around you and looking for machines with a good following on home-barista. If you're patient, you can usually find a crazy deal on a pretty good machine in need of some light care. For more popular home machines, you'll usually find a number of guides for repairs or maintenance as well as links to specific parts that you'll need. In some cases, like with the Gaggia Classic, you'll also find various tweaks to drastically improve performance.
