Consequently, we have decided to start drinking espressos in order to reduce the overall intake volume.
We bought this Bialetti stovetop espresso machine (cost: approx. $38.00):

Short answer, no. It makes strong, "italian-style" coffee, which I like. But it doesn't have sufficient pressure to make the crema and flavor of an espresso made with a power machine.
What's a coffee geek to do? Buy an expensive espresso machine. We are researching brands and prices.
