Power Conditioning for a mid-fi system.

I am trying to get the best components I can get, but on my budget I do what I can do; however, I think my system, when it is done, well be better than your average bears'. Anyway, I have been plugging all of my stuff into the same power strip and it is getting kind of messy. I would like to get a good power conditioner, but what, and at a budget price, new or used. I think I am going to get an ultimate outlet for my subwoofer just because it is so far away from my other stuff. I have had my eye on a PS Audio rig, but new it is out of my price range for now and used, well, that isn't happening. It seems to be a hot item. What else is there?

Any ideas would be helpful.
