I use one of these:PowerSwitch Tail II
it works great. I bought the kit, as I wanted to use a right-angle, 20A plug and I needed a bit longer supply wire.
The internals look to be plenty strong to handle anything that a 120V / 20A circuit can dish out, the relay is rated at 40A / 240V AC and the power and neutral traces on the PCB are 0.20" wide. This will not work on a 240-volt circuit in the US though, because it is single-pole. It only switches the line side, not the neutral.
Assembling the kit was easy, took me less than a half-hour to get the board stuffed, soldered, and cleaned up. I spent nearly as long putting proper ends on the power wires.
I had a bit of a hum issue with my iNuke and my Denon 3312, I've addressed that with a proper RCA-XLR cable.
Anyhow - just my experience, but it works like a champ. It is nice not having to switch the amp on and off manually any more.
Also, for what it is worth, when I needed it, PST's support was excellent too, I had my parts inside of a week.
