Looking to connect a second broadband connection for failover and add a second firewall, any suggestions?

We are looking to add another broadband connection for redundancy. We
have Road Runner and a sonicwall soho3 at this time. We are going to
install a verizon DSL line and want a box that will "join the two"
either to combine the bandwidth or for failover. Is there a reason to
have two hardware firewalls in line? Or should we have the firewalls
before the lines are "joined"?

TIA
