Robert:

Thanks. Standing it up vertically clicked something in my head - I've got a bookcase right next to the plug I want it by, I could have the IR543 mimic a book. :-)

I chose the Leviton 16293 because it will be controlling several table lamps around the room plugged into outlets - and electrical code in Canada state you cannot have a dimmer controlling a receptacle in the chance that you plug an appliance in (which would mean bad things!).

I just checked, I'll only need to dim 300w worth of lights, so the smaller version will do. I wasn't aware of it (Leviton's web site is a bit sketchy on receivers) - do you have a part number?

Hmm, what about the SwitchLinc 2380 dimmer (as on smarthome.com)? And why don't smarthome.com's part numbers match up with anything? :-)
