As if I needed another reason to drink coffee.
I'll couch this in a warning that you need to have the money for it, but for me an espresso machine and good grinder was such a great investment.
It's this thing I appreciate a lot every day.
If you're a drip coffee person I guess this won't apply and you can save a few thousand. Although I'd still recommend getting a grinder (not necessarily an expensive espresso worthy one) and good beans then.
