Over the course of six years I've had a total of four receivers. Two original receivers were deactivated over two years ago and as of this weekend, one more will be going (an old RCA 40 TIVO) which leaves me with one HD DVR one. I'm getting a standard HD receiver to accommodate a new hd television. I'd like to get rid of the older SD receivers but not sure how to do so. Would anybody like to give suggestions on how to do so? I'd rather drop these in an electronic disposal area. Don't think these would work again but like to help clean things out. What are some good suggestions?
