I just overhauled a la marzocco sitting in my kitchen. People often inquire about whether it's worth buying an espresso machine for the home, or if it's a good investment as a coffee connoisseur.

My reply is always that it was the best money I've ever spent and the worst investment I've ever made. It's a lifestyle choice, and a questionable one at that. But one I'd make again every time given the opportunity.
