Help with purchase of power conditioner


Hello, Ive recently been looking into buying a power conditioner but I don't know much about them. My budget is limited to 300 dollars new or used. My setup is as follows

Fronts: Paradigm mini monitors
Center: Paradigm studio cc
Surrounds: Paradigm ADP 350
Sub: Paradigm PW 2200
sony dvd player(budget player)
Onkyo Integra dtr-7 reciever
monster cable interconnects and speaker cables
Old magnavox 27" tv(next upgrade)

I've never had any experience with power conditioners and would really appreciate your input.

Sek, There's several Tice A/V Solo conditioners for sale in the Audiogon classifieds...the improvement brought in TV picture is stunning.
Thanks for all the great advice. I'm new to audiogon and I am impressed on how quickly everyone jumps at the chance to help out. I will be sure to do the same if any of you ever need help. I'm a pro audio engineer and have a lot more experience in that field than I do in home theater. Well once again, thanks everybody you've been a great help.
What do you guys think about the ps audio ultimate outlets? Would one of those work for me?
I'm sure its worth a test, but I wouldn't get into a situation where you can't return it...PSaudio is kinda vauge on how the "Balun" works, and I am skeptical of products when i'm told how good it is rather than how it works. Keep in mind, it only has 2 outlets. Personally I'd stick with more traditional forms of protection/isolation. Monster or Panamax.
