I have the sage barista express and it's my prized possession. HOWEVER! I also prefer black coffee and I'll echo what Siliconslave said: the £30 hand bean grinder and £30 aeropress I had before the sage made better tasting black coffee. The sage machine just makes it a whole lot easier and tastes almost as good, and you can make espresso and frothy milk drinks too.I keep thinking I should get something like this. I do love my coffee but I only ever drink it black and I've been given a few "expensive" coffees from machines like this, and in indy coffee shops, and never found they taste better than the other. My palate is pretty unsophisticated in terms of stuff like this, so I feel it would be wasted on me
But then I also feel if I had something live the above, I'd drink better coffee and appreciate it more
TL;DR - talk me in to spending £500
