There is no such thing as a good inexpensive esspresso machine. If you really like good coffee, spring for a good one ..Gaggia or Raclia or any Italian Machine. You won't regret it, they last a long time, are economic on coffee and take a min or two to make a cup. I've had mine for 17 yrs and have changed the pump twice at a cost of $75 a pop. How many Mr Coffee's have you gone through in 17 yrs?
edit;
What ever you do...don't buy some POS general electric/Starbucks machine....they don't have good pumps and if you want exquisite coffee, it must be ground powder fine (#1) and a cheap machine will not pump through it.
