My SE/30 manual (I know, the IIcx probably uses more) claims 75 watts max.
So, an SE/30 costs at most:
75 watts * 24 hours/day * 30 days/month * 1/1000 watt/kilowatt *
.10 dollars/(kilowatt*hour) = 5.40 dollars/month
(Our electric rates are $.13 per kilowatt-hour in the summer. In the winter,
they're about half that; $.10 is a ball-park average.)
