I finally gave in and got a breville bambino plus and I have no regrets. It was $400 on sale, produces quite decent espresso, foams milk well, has been very reliable, and doesn't heat up the kitchen - I held off getting an espresso machine for years because the instant heat ones always seemed to suck. This one doesn't. I mostly drink Americanos and straight espressos, my wife drinks lattes, everybody is happy.

But I have to agree with others: for my diluted espresso desires, I used (and still have) an Aeropress for years and it's simply fantastic. Low cost, almost zero maintenance, good results. Very similar output to an americano though lower on crema.
