The make and model of your vcr, sat receiver and dvd sre important in making that determination. Some sets offer individual power control "discrete commands", others would require sensors to automate. AFAIK, the CM-232 is not yet available (other than a handful of test units) and you will need an additional accessory, an IRF-6 to take advantage of these parts. As for the price, you're paying more than a do-it-yourself consumer shopping on the internet but the pricing's not unreasonable.
