A while ago, I posted some "best of" threads related to power, outlets, conditioners, etc. Here's a copy. It could save you some work in your research. I'm sure there are some more current threads, but these are some oldies but goodies. Search on the headlines and you should be fine. Listed are the headlines, the initiator and the date. Good luck.
I'm doing some research on this topic and would like to recommend the following previous posts:

That's my "dirty dozen" -- sorry if I may have missed some other really good ones. These should answer most of your questions. Note -- the first thread referenced 74 other posts of interest (I did not check these out, but Bob Bundus is one of the "guru's" in this area). Hope that helps.
