Honestly, you might be better off with a Moka pot and a separate frother. This machine isn't likely to give you anything resembling a quality cappuccino. The steam power won't be enough to microfoam the milk, so you'll get really thick bubbles and milk that looks like soap; this means that you'll have a huge layer of foam that always sits on top of the espresso. Additionally, the temperature stability of the machine isn't likely to be anything that can produce a consistent espresso. You won't likely be getting
anything like this from that machine.
Finally, the grinder will be immensely important no matter what you do. Do not buy preground. If you buy fresh beans and grind them before each pull you'll likely have something that passes as ok or good. Espresso is, unfortunately, rather expensive relative to most preparation methods.
Hope that helps.
