Re: USB controlled mains switch

I'm looking for a USB controlled mains switch (230V AC) that I can
connect to a PI to turn a mains power supply on and off.
 
I've done a bit of digging around on the net, and the options seem to
fall into two categories, either a relay device which means having to
rewire the device (which I'd rather avoid), priced around 30Euros or one
that sits in line (between the device and the supply).  The latter
appears to be in excess of 100Euros, which is considerably more than I
want to pay.
 
Any suggestions on where to look ?  I'm not interested in a wireless
solution, as it is likely to be used in places where signals are not
reliable.
 
Thanks

No need to rewire the end device to use a relay controller. Just wire up
a simple intermediate between the relay and the controlled device. i.e.
add a plug and outlet to the relay. Or buy a pre-built one:

Low voltage controlled (about $40)

Ethernet controlled (about $80)
