Ah, power conditioning. For those reading who don't believe sticking a box between the wall and your shiny gear makes a difference, well, your loss.

The UPC-200 is PS Audio's second newest power conditioner (their UPC-200HB version adds hum-busting power) and costs $499. PS Audio has been around a long time and won numerous awards for their larger, more "effective" Power Plants (which start at $1500) as well as their excellent digital amps. Though not the only power conditioner out there, the UPC-200 is PS Audio's cheapest solution and a great place to begin. Paul Taatjes says it best:

"...there is no question as to the UPC-200's effect on my video system. I am not talking about any increased detail or more 3D video images, but a total correction of a major issue I was having."

With four outlets, you may not be able to plug all your gear into one UPC. Then again, the benefits of conditioning vary depending on the type of equipment. Check out the review - this may be just what you need.
