Any better/cheaper suggestions?

I found none cheaper. I installed one of these to contol
my outside lighting circuit, but found problems when I
included a light sensor in the circuit because the electronics
in the switch and the electronics in the light sensor seemed
to have problems with each other. In the end I changed
it for one with a relay in (like a central heating timer).

It will definitely only control normal filament bulbs up to
400W and it won't do low-voltage or compact fluorescent
lighting - I tried both.
