When a friend of mine found a La Pavoni at a garage sale and gifted it to me on my birthday, I took some birthday cash and headed straight out to pick up some espresso swag. I had to have a burr grinder, a tamper and a frothing pitcher. Then I stared at the knock boxes and couldn't do it. I could justify everything else, but dropping another $30-$50 on a knock box seemed like an insult. I'm not sure why. I suppose I just thought I could knock out the burning hot espresso grounds into the sink, garbage, etc.
