Thanks for all your comments guys. With regards to bgp I did think about placing two bgp routers in front of the ssg's. However my limited understanding makes me think that if I had two bgp connections from different providers I would still have issues. So I guess that if my primary Internet goes down I lose connectivity to all the publicly addressed devices on that connection. Like dmz hosts and so on. I would be interested to hear how this can be avoided if at all or do I have to use the same provider.
No, you will announce the same IP addresses (minimum of a /24 which you can easily obtain from one upstream just by saying "I want to multihome" if you don't already have a /24) over both. That's the whole point of multihoming. If cost is an issue you can just use one BGP speaking router. If you multihome there is no "primary" like you're thinking. ~Seth
