I just bought 3 of these Cyberpower HT Surge Protectors. I didn't want to fool around because I had some nasty surges last summer which damaged my projector and A/V processor. These units protect up to 6000 joules which is about as high a rating as I could find after a week of research. http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=1557668&CatId=232
