How much does your cable box suck?

I did some power monitoring our our entertainment equipment. I had been concerned about the "vampire" load of our high-def cable box, and was not surprised to find that it pulls 68 watts in BOTH the on and off state (my only surprise was that they bothered to put a power button on it at all since it appears to do nothing of value). At our current electrical rate the set-top box costs us $107 per year to operate.

Unfortunately, it is a particularly bad candidate for turning off because it takes many hours to recover all the channel information after a power-cut.

Also in the "ungood" news department, our 50 inch HDTV is pulling 225 watts, well above the 153 watt Energy Star 4 rating which goes into effect in May. "Honey, we are killing the environment, can I buy a new TV that will save us 72 watts per hour?" (AYOOYM? It will take us
139,000 hours of viewing just to break-even. That's 16 years if we leave it on 24/7.)
