I'm going to guess that you're most interested in the single-serve/pod espresso machines and that you want real espresso rather than just coffee.

Nespresso and Illy make single-serve, real espresso machines that use pre-made pods. Prices range from $200 to over $700. The Nespresso Essenza ($200) is a nice, low-cost unit. If you'd like an integrated mil frother for cappuccinos and lattes, the Nesspresso Citiz with Milk Frother ($350) or Gaggia for Illy $(300) are good values.

Be aware that there are other espresso machine types which vary along an automation vs control dimension:

1. Single Serve (Pod): Add pod. Press one button. Drink.

2. Super Automatic: Add whole beans. Press one button. Drink.

3. Automatic & Steam Espresso: Add ground beans. Tamp. Press one button. Clean portafilter. Drink.

4. Semi-Automatic: Add ground beans. Tamp. Turn knob to start/stop brew cycle. Clean portafilter. Drink.

5. Manual (Piston): Add ground beans. Tamp. Use lever to control pressure and time. Clean portafilter. Drink.

If you like the automation of a single-serve/pod machine but do not want to be tied to expensive pods of limited variety, consider a super-auto espresso machine. Or, you can save money and gain control over a super-auto by opting instead for an automatic or semi-automatic. Note that manual (piston) machines can actually be more expensive than semi-automatics, however. Note also that while there's a lot more work in the less automatic approaches, sophisticated users prefer the additional control. In most cases, a skilled barista can produce the best coffee with the manual or even semi-automated machines, but less sophisticated users will get the best results from the super autos or pods.

You could certainly break the bank buying an espresso machine, but there is really no need to. Brands like Cuisinart and Capresso make quality machines for 150 dollars or less.
