I suggest getting a Cisco 2500 or 2600 series router.  They can do the load
balancing quite easily and 2 T1's can be attached to either.  I know this is
a non-freebsd solution, but I have always found that a hardware router with
no drives and few moving parts is quite reliable.  I know this is not where
I should be peddling my wares, but I have a 2500 and a 2600 for sale. ;-)
