If you don't have a daily espresso from a moka pot, chances are that you might have one in your kitchen somehwere.
A simple Bialeti Moka Pot will give you a great cup of espresso. No need for an expensive espresso machine.
If you are not familiar with a Bialetti, the style is a bit different since you do not have the same effect as a short pull from an espresso machine.
When using a Bialetti the best espresso blend is up to you. Lavazza is common and pairs very well with a Bialetti.
If you decide to get other coffee, I would recommend using a medium roast instead of an espresso roast. Medium roasts are used in Italian espresso since it is not as bitter as a typically darker espresso roast.
