Well, I knew it would happen. I've installed Comodo firewall, the latest version. It's running light and smooth, and I've got Cruelsister's configuration set up. After watching and reading the Comodo forum and seeing only a few minor complaints, I decided to take the plunge.
Another reason, or rationale, is CS recommends it, and uses it. I'm sure she thoroughly tested it against others, and it came out the strongest.
