I think my Nespresso Latissima is one of my least mustachian purchases, so I would be shocked if many weigh in here. It is definitely a luxury item which I choose to use because I have two small kids, need my coffee in the morning, and it is WAY cheaper than my old starbucks habit!
I applaud you for trying to make it as mustachian as possible, but I think you have gone as far as you can go. I tried HiLine and switched right back to my glorious nespresso arpeggio pods at $0.65 a pop. The flavor is worth it to me. When this machine dies I will go back to an old fashioned espresso machine, but for right now the splurge makes me happy!
