The earth connection is through the crocodile, however, the price difference between a serious station and a service soldering iron is the isolation between the power supply and the tip. As Joep suggested, a low voltage soldering station has also a better isolation between the phase and the metal body. That's why is at least 10 times more expensive. However you can buy a nasty soldering station as well...as your luck is... For sensitive low voltage CMOS devices I'm using a 220V/220V separation transformer. In that way I can use any inexpensive soldering iron. But if ou plan to solder (and mostly to desolder) SMD, you need a hot air station with low voltage soldering iron included.
