Redundant 0.0.0.0 route to separate edge routers.

I have a 5400R acting as my core switch.  All of my devices at this location are using it as their default route. 

I have two edge routers attached to it each going to sepreate ISPs.

Each edge routers has a static route:

Primary Edge Router 10.0.0.1

    route: 0.0.0.0 0.0.0.0 208.x.x.x.x (ISP1)

Secondary Edge Rotuer 10.0.0.5

    route: 0.0.0.0 0.0.0.0 12.y.y.y (ISP2)

Core Router 10.2.2.1

    route 0.0.0.0 0.0.0.0 10.0.0.1

each router is also advertising it's direct /29 connection to each ISP via OSPF to the core. 

currently if one if the ISPs is down i have to manually change the static route in the core to point to the other router.  I'm sures there is a better (automatic) way of switching between edge routers but haven't been able to figure it out yet.
