Comodo, fairly-good reputation over the years.

Positive Comment by peterstaack
about Comodo Firewall Jun 2011

I used this for quite a while on my older Win2000 and WinXP systems, and it was quite effective at keeping my clients out of the dark recessing of the internet. On the newer systems, running Vista/Win7 or a popular Linux distro, I tend to opt for the integrated firewall for convenience sake. However, as needed, I wouldn't hesitate to trust Comodo, given their fairly-good reputation over the years.
