Has anyone bought a Comcast digital receiver on Ebay and hooked it up? They can be bought pretty cheap. I currently have 1 HD receiver and 1 digital receiver, but would like to get another one without the lease fees. If I could buy one on Ebay and just hook it up, cool. Or would it have to be activated like a Dish receiver? Any help would be great! My digital box is a DCT2224-1161 which is readily available on Ebay.
