I hate to admit it, but I have a Monster Power strip that I paid less than $100 for. I'm sure the $1K Panamax and $500 Belkin units mentions above are better, as well as many others, but the Monster unit did what I wanted: Before I had a S3, the Monster unit made a noticable improvement for my Analog devices (e.g., Tivo S1) that I was having problems hearing over interference without turning the volume way up. My unit has only stage 1 power cleaning, which basically means that prevents outside interference from getting in. I live in a Condo, so filtinger interference from my and my nieghbors units is a must. Stage 2 seperates your devices into banks. I believe the Panamax units have like 10 stages, which do various things.
