Amazon has the "Monster Reference PowerCenter HTS 3500 MKII" on sale for $149.

I've got two of them (one for each system). They do what they're supose to do I reckon. No idea if they are the end all solution or not. Don't really care either. I bought them instead of a standard surge devise because they look good on the rack and all my AC cables are neatly routed. - I don't like cord orgies.
