Well, the second provider wouldn't help as much if we had to relocate for a while. That's why I was thinking about something mobile. Our server is barely a server, its essentially just a HP Workstation with SBS 03 installed. All we would really need to do is move the tower to another location if the place gets flooded/damaged. Having a backup ISP like Cable would be as restrictive as the DSL if we can't stay here.

Yea, that's the basic idea. How would that work with something like a ISP that uses a USB antenna? (for example)

I was thinking about something like DNSMadeEasy's service for Mail Backup, which offers 3 MX records that will queue any messages that are received while my server offline, then deliver them as soon as it gets back online. But then theres the point of getting online again and their servers finding mine. If I'm using a different ISP, how do they find me?
Our e-mail is a service of our SBS (Exchange 03) so we need to be able to access the server to get our email.

This could be done with two T-1's from two providers, routed though two diff COs. This would cost 1000-2000 a month.

Nope. We're looking for something cheap if we could do it. I convinced them to go from a P2P network to a server/workstation set up. We have one server that acts as our office DC, Mail Server, File Server, etc. It was economical to do with the expectations of expansion (which we are still doing). We've already added a few people and adding them to our system was easy (thanks to the server). This issue needs to be solved as inexpensive as possible.
