Interesting isnt it?
I have literally spent thousands of dollars on coffee gear this year, and even though I have built up a small (45kg) stockpile of beans, I seem to never be able to get enough. The whole pursuit of making a fine coffee seems to become an obsession, effecting each of us differently. And the cost of making a coffee at home is certainly cheaper over the long term.
We always have a better coffee at home than when were out, unless we go somewhere really special. I think thats the real pleasure (apart from having something shiny on the bench) - creating a variety of espresso, presenting a milk-based coffee with fantastic artwork (Im still working on that) and as many folk here say, enjoying whats in the cup.
I dont think you can put a price on that!
