Firewall suggestions for traffic shaping/QoS - pfSense or m0n0wall?

I just ordered these -


They should arrive mid week next week, I’ve purchased the pair so I have one for production use, and the other for use at home/experimenting with… I’ve been running pfSense 2.0 BETA5, and understand that it is a fork off m0n0, I’ve successfully setup traffic shaping in pf, and am just wondering if it is any harder/easier with m0n0wall. I’ve also noticed that the m0n0 images are much smaller, and will fit on a 16MB CF card, where as pfSense requires a much larger card… Any tips would be greatly appreciated. If I get a good, solid, working setup, My boss has agreed to reimburse me for the Firebox we’ll be using at the office…
