This may be different from your expectations but you might want to look at Nespresso (
http://www.nespresso.com/us/en/). This is an expresso machine that uses capsules -- which cost around .55 cents per shot (capsule) These machines are easy to use and produce an excellent shot with
the best crema. And, it's fast!
The machines are small so they don't take up a lot of counter space. They are much easier to use than standard machines when you need to make shots or drinks for a group of people. It's also pretty hard to beat the price per shot.
A downside is that the prepackaged capsules may not have the coffee you are looking for. You can get kits that allow you to make your own capsules, but that seems like a PIA.
I like a number of the coffees provided by Nespresso so I have no problems. They also have milk frothers if you are looking for that as well.
The machines range from $200-$600.
