If those ISP's are connected to your domain on any router and connected on the routers in your domain running eigrp or ospf. assuming that you can have two default routes on two different routers pointing towards your ISP 1 and ISP2 with different Administrative distance and than redistribute in your OSPF or EIGRP routing protocol.

e.g.

R1 (assumed to be primary router to ISP1)

ip route 0.0.0.0 0.0.0.0 next-hop of ISP 200

redistribute static

R2 (secondary)

ip route 0.0.0.0 0.0.0.0 next-hop ISP2 210

redistribute static in OSPF or EIGRP
