I'd say go with pfsense, mostly because I believe that a dedicated
firewall version of FreeBSD is safer than altering a vanilla version to
act as a firewall. 
Pfsense 2 is very close to RC1 status and we've been stress testing it
here with full internet routing tables via OpenBGP and snort (This is
very much improved in this version) Carp failover tests have been
extremely fast with no discernable drop for the end users and it has
relayd builtin.  
HAProxy is also packaged for it and seems to work well in tests. 
I admit the boxes we are running it on are perhaps a little over kill
though, DL360 G7 2x12 core processors with 14 gig of ram but they still
work out a lot cheaper than an ASA5020 and depending on the amount of
work you need it to do you can vary the hardware right down to embedded
The only down side is that FreeBSD is not certified to EAL4 but that may
be of no concern to you.
