Must I sell a kidney to enjoy a decent expresso. I have seen machines listed from $249.00 all the way to $.3000.00 for a "home system" I am not opening a Starbucks. although that BMW designed machine looks great. All I want is a fine cup of expresso we have had in Portugal or Spain. What are the differences between a $12.000.00 Francis Francis and a $399.00 Briel Pro?And do I need 18 bars of pressure to enjoy a expresso? Help.
