All Good points. My situation is a bit different though .... and I assume you're replying to my recent hijack of this thread, the original one being almost three years ago.
Oh, and yeah, it's really espresso-based drinks I'm after, primarily Americano and Cappuccino, though sometimes Latte and even the odd Mocha, or weird recipes.
On that assumption, I'm effectively retired, and some health problems give me some mobility issues. The wife works from home and says she's not bothered, "instant will do", but she generally really enjoys "proper" coffee when we get one out, somewhere (though neither of us are Costa fans).
The machine I'm currently trying to convince myself not to indulge in is a step up from the Sage Dual Boiler, with a LOT of extra ease of use. It still has the dual boilers, still has accurate PID control but is pretty heavily automated. Kinda.
There is a decent (not top end but it appears good enough) burr grinder built in. You can set it for about 18g of grounds though factory default is a bit higher. But it grinds and tamps into a puck for you. Minimal effort suits me.
The manual bit is to move the portafilter from grinder to head myself, and empty grounds out afterwards. That removes one of the trickiest bits to automate. Makes cleaning pretty easy, too.
But everything else, pretty much, is automated. You can fine tune and adjust, but everything down to milk temp, and frothing for cappuccino to latte, is automated. You can, of course, tweak defaults. Want an Americano (which I usually do), you select Americano as the type and it adds the relevant hot water, After doing the double-espresso rubbishrubbishrubbishrubbish. You can also add your own custom 'recipes', with non-standard defaults.
The idea is to get most of the quality of Barista machine coffee, with far less effort, or even knowledge. Though, the more you learn, the more you can tweak.
In other words, little sacrifice in quality, maximum increase in convenience and ease of use, but it comes at a steep price. Yeah, I could look second-hand, but then your taking a gamble on some numpty having mangled a pricey piece of kit. And yeah, I could buy all sorts of other kit and start modding, but like I said, restricted mobility. I don't want the hassle of second-hand, let alone nodding PUD's etc. Years ago, yeah, sure. Now, no.
I know what appeals to me. Well, between two models, one less automated that the other (and about £400 cheaper). What doesn't appeal is the price but hell, I can't take it with me.
This thread has been useful, though. It's pointed me in several directions, focussed my thinking and really it comes down to .... am I prepared to spend that much?
