A dual WAN router seems wonderful. Failover if one ISP goes down, awesome. Until the router itself goes down, then you lose both connections. Been there, done that -- NOT A GOOD SITUATION.
As the previous poster said, buy two routers, two network cards, and hook them both up to your PC. XP/Vista will automatically switch over to the other connection when one dies (it can take a minute or two for windows to figure it out). I've never looked but I'd guess there are also programs out there that could disable the internet connection if it goes down.
