I have a T-Rex Fuel Tank Chameleon that cost $215. It has three isolated 9V/300mA outputs that can be switched to 12V/225mA, one isolated 9V/300mA that can be switched to 18V/150mA, and two outputs that cannot be used at the same time, one is 12VAC/300mA, while the other is the same as the first three outputs. It can be switched from 115V to 230V.
There's a lot of things I like about the Diago unit, except for the fact that it is not isolated.
