One of the least expensive models that is basic, yet gets the beans brewed quite well is the Saeco Vienna Plus. No LCD screen, no bells, no whistles. Just a water tank, bean hopper, 3 buttons, 3 knobs, and 2 spouts.
With regular cleaning, descaling, and upkeep, some folks have gotten 7-8 years of use with this superautomatic.
We been using this machine for a few months now and I'm still tickled when pressing the "Go" button each morning. I usually take a 2-ounce shot of espresso with it. It delivers a nice taste of 3.5 star espresso. (Albeit, nothing close to the 5-star god-shot we all wish we could get at our home kitchen without spending $2,000. But heck, this thing is under $500.) But you can also fit a standard size mug under the coffee spout as well. You'll need some extra help with a tall travel mug though.
If you're a daily coffee/espresso drinker than do your mornings a favor and pick up a machine like this. You can check out the Vienna Plus at Amazon.
