I made a comment about knowing guys with $10,000 worth of coffee gear on their counter. A buddy waited until today to ask if I was joking.
KF 1800 coffee grinder, $13,995
Slayer Espresso Three Group (cappuccino maker, does not include a grinder), $32,215.00
You could spend $10k on fiddly accessories without blinking.
You can buy a decent house in some parts of the world for what you pay for a really top end espresso setup.
