If you are looking for an easier routine, have you tried the OXO rapid brewer to make "soup"? It is as easy to operate as an Aeropress, and it makes a really yummy concentrated cup.

A typical recipe is something like 20g coffee and 80g water, yielding about 60g of concentrated coffee. Lance Hedrick has done a few videos on the subject.

It is not espresso, obviously, but it takes no time to prepare, it tastes fantastic and it is very easy to dial-in.
