I have some experience with the Xincom Twin WAN router. Basically, all it
does is NAT RFC1918 address space (by default) and load balance stateless
TCP traffic (ie. web traffic) over two outbound links. Established TCP
sessions will not fail over, unfortunately, but the device is fairly
reliable and does NAT-T fairly easy. 

Sure, there's cheaper ways to do this solution without paying for a
blackbox, but there's no moving parts in the device and thus is good for
small offices that have no clue built-in.
