Bialetti stainless steel stove top espresso for the win!
Bialetti Musa 4-Cup Stovetop Espresso Maker: Amazon.com: Kitchen & Dining
This is my daily coffee maker, and also serves well for camping too!
I use 2 tablespoons of grounds for each batch in my 6 cup maker, which is equal to one full size coffee cup. If you were to stuff the basket full 3-3.5 tablespoons and remove from heat before the pot is full, that espresso would rival ANY electronic machine and some commercial, specifically the ones with out lever action.
Point is, if you've got $500 laying around and think those electronic machines are worth a damn, forget it! Find a Krups on sale for $100 and call it a day. The electronic ones WILL fail, how much do you want to be out when they do?
You need to step up to a $2000 rotary pump with E61 brew group. Its called that because it was patented in 1961 as a nice simple commercial design that is virtually indestructible. A friend of mine has the Vetrano and I simply have never had a better shot. Lever action is the ONLY way to go so you can control 'blonding.' (a view of the crema as it is being pulled will go from brown to blonde, the lighter it becomes the less flavor is being extracted)
