I have a cheap Gaggia machine for espresso, but it got thrown in the closet after a while. I did like trying different beans as espresso though. You really get a punchy sour espresso from light roast African beans. Asian beans come out tasting umami/salty. I think it would be fun to play around with blends to get all sorts of different profiles. In my experience in Hong Kong, they really go for the fruity/acidic taste in their espresso at the 3rd wave shops. Took my wife and her dad to Hershey and Hazel for some affogato and he hate-hate-HATED it
I could NEVER get latte art right. I assume it's partially because of the shitty steamer on my shitty Gaggia. You have to run it through one full heat cycle just to get the milk to start foaming. Maybe if I had the patience I could get it right, but I don't care much for lattes or latte art - I prefer the coffee to stand on its own. I would actually prefer no art at all, just dump the milk on there thanks (and my most common milk based drink is macchiato anyway)
