Depends alot on what kind of connection you want. If you are just talking about outbound access from your site, that isn't a problem. Setup the two routers on the same subnet and use HSRP. Best practive would be to set up two HSRP address; each router will be primarary for one address and backup for the other. That way you can direct traffic over a specific connection when it's all up, but traffic will failover to one connection if the other goes down.
If, on the other hand, you want to maintain public services during an outage (ie, web pages, FTP sites, incoming e-mail), that is a gorilla of a completly different color. If you're site is big enough, you could justify a /19 public address, which can be routed via BGP. That would solve alot of you're problems, but it's unlikely that you'd be asking the question if you had a /19. Some protocols will allow you to specifiy a backup via DNS (I'm thinking SMTP), but that only helps with mail. Otherwise, you're options are co-locateing the equipment you always want available, or switching both your WAN connections to the same ISP. THere is no really easy solution.
