The SONICblue eStore only supply the Analog Vision units (not the one pictured). They are big and have IEC sockets. They supply 2.5A IIRC. They are fine, but if you need a USA adapter, I have the small plug-top adapters for 15UKP inc postage.

I have very few of the Sunpower IEC units remaining, so they are reserved for warranty use and are not generally for sale, since I would like to avoid having to place another order with them as I doubt I could sell the minimum order quantity.

The Sunpower units are available from Maplins. The manufacturer code is MA-150. 15V at 1A. You can order onlline at http://www.maplin.co.uk/

If anyone has difficulty sourcing one, then contact me directly.
