Affordability aside, most commercial (aka professional) grade espresso machines are cumbersome to install in a typical home, often requiring special cabling (due to high current draw) and special plumbing.
That said, a selection of commercial grade espresso machine companies also make some simple, low capacity models which are easy to operate for the home user and do not require special installation.
In this category, at the top of pile in semi automatic machines are the Sylvia by Rancilio and the Classic by Gaggia.
