I exclusively use the plastic aeropress (3 years or so) and although upgrading to something stainless seems like a nice upgrade I'd want to revisit best brewing methods and make that decision again before spending $150+. I don't drink coffee every week let alone every month, typically doing week long streaks before taking a break, so this is cool to see but nothing that makes me rush out and upgrade.
There seems to be some haters in the comments for the aeropress, I guess I'd like to know better alternatives for quickly brewing black coffee for one person.
