You can't beat the flexibility of iptables and Linux.

Hardware is your big concern here.  Just avoid moving parts and heat as
much as possible.  I have a 486 and with a 800 meg hard drive that I end
up rebooting about once a year.  I just run a script which locks the box
down and sets up iptables.  If that box ever failed, I could have a
replacement up within 30 mins.  In time I'll find something without a
hard drive but it's not that urgent now.

You will spend a little time learning iptables (as you will with IOS)
but you will take the scripts that you develop and the things you learn
with you.  When you outgrow your PIX, you'll just buy a new one.  I like
investing in myself not hardware.
