The difference between BBQ and espresso is that it is possible to make decent BBQ on a cheap grill. It may be more work, not be as fun, lacking features, and/or missing something (like moisture!) relative to a KK. But it can be done...we've all done it. With espresso...there is "meh"...Starbucks and cheap, low end espresso machines. And then there is..."Oh! I didn't know coffee could be that good!" To achieve the latter is a quest that requires 1) Good barista technique (yes, I watch them in coffee shops and note their mistakes), 2) Great beans (specialty roasters or roast your own), 3) A top of the line grinder with a perfectly dialed in grind, and 4) a suitable machine that can pull the profile you want. Getting those 4 in balance is exceptionally difficult to achieve without spending some cash.
Obsessed? Not at all...
