Eddie,
I have a Monster HTPS-7000 Power Conditioner. I paid $800 for it and I am very happy so far. I run my Denon AVR-5700 Receiver and several pieces of audio and video gear through it and I must say, picture and audio was noticebly improved. As I live in Central Florida, surge supression is very important to me as we have frequent lightning strikes and storms. There is ongoing debate on the net about the value and necessity of Power Conditioners for Home Theater application. For me, I have piece of mind and enhanced audio and video to enjoy.....
Just my 2 cents, of course, your mileage may vary.
Bill
