Features:

• 6 x 9V DC outputs on a common ground (not isolated)
• 600mA total current available
• Internal 230V/115V AC switch for use in different countries
• Detachable mains lead
• Made by a very nice bloke in Bolton, UK!

Advantages over the Diago Powerstation:

• Very thick metal casing. You could probably drive a car over it with no damage!

Disadvantages with respect to the Diago Powerstation:

• At £70/$130/€100, it's a little more expensive
• Only 6 outputs and 600mA total. Could quite easily be overloaded with a few digital pedals
• It's big and heavy, and takes up quite a bit of space on your pedal board
