Looking to spend up to $50, (more if neccesary) for a good Home Theater Surge Supressor with RFI and EMI filtering. Most of what I see at my Home Theater stores are usually all Monster Cable Power Centers that exceed $100 or $200. Looking for suggestions from other users on what to buy. I've heard of a few good models, but I'm still looking around. A "So what is everyone using, and does everyone else agree it's good" response is what I'm looking for. Thanks!
