@capuchin for that price, I’d buy it just for the love of it. The Slayers are amazing machines. If you like medium to dark roasted beans with milk, the niche would be up to the job.
The slayer is art. it’s a joy of a machine. it’s so much more than just what you get in the cup.
But if, for you, what you value is what’s in the cup then probably pass. No judgement there, people value different aspects of espresso: the espresso, the flow, the aesthetics, the quality, smart designs, durability, functionality and more.
I place a high value on beauty, but not above functionality e.g. I have a funny looking Minion-Looking grinder called the Moca SD and a box looking espresso machine in the Decent. So it’s not all about the looks. But a slayer … wow, that’s got it all.
And he’s right, assuming it’s in good nick, you aren’t going to lose money on it.
And if you decide that you want something to match it, and the niche is not doing it for you, there are a bunch of “next level” grinders that will bring out more in the medium to light roast range e.g. the Moca SD or a P64.
