Greg,

I personally use a Spaun 2x4 solid state multiswitch and it rocks. I used to have a 3x4 Recoton (mechanical) I bought from Best Buy for $80. By replacing it with the Spaun, which is also non-powered, I gained about 4% signal strength back.

The surprise is that the Spaun cost about $40 from this guy. In case you are not aware, Spaun stuff is generally regarded as "the Mercedes-Benz" of multiswitches. They're even made in Germany. Getting them so cheap from that eBay guy was a treat.

I suggest you try out a Spaun first before spending too much on a powered model. I use mine outside. It's been rained on and snowed on and still works perfectly. Just my $0.02.
