I am one who likes to plug my gear into a surge suppressor, just to have the extra piece of mind. However, when I purchased my plasma TV a few years ago, I was having some issues with the set. Every now and then and sometimes even several times in a minute I would get a flicker in the picture, where it would quickly have a black screen and then go back on. This was very annoying and distracting. I started looking online and apparently plasma sets are sensitive to fluctuations in the voltage. So I got the APC H15, which is a surge suppressor and voltage regulator in one when they went on sale for about $150. So this unit helps to keep the voltage within a certain tolerance. This almost completely solved the flicker problem on my plasma set. I might notice it flicker once per two months, where it used to be almost a daily problem (and on some days it would flicker so bad that I didn't even want to watch it).
