Dual Wan Can Anybody Recommend A Powerful And Reliable Dual WAN Router?

Can anybody recommend a powerful and reliable dual WAN router? - dual wan

I need a router that will automatically back Internet connection if the primary fails. The primary connection is a bonded T1, and the backup is also a bonded T1 (Wireless not only technically committed a T1, but) the idea. I need something that the bandwidth of a connection as high as those who can not bypass a bottleneck. Another would be if you can "connect" the two compounds in which they are so that we can take advantage of both compounds. Anyone ever do something like that?
