I've heard that clipless SPDs from shimano are really good, and are easy to slip out of quickly. I'm looking into these kinds as well.
Eggbeaters seem to be the running champ from what I've seen, though, and it's hard not to see why. They're really adjustable and just great for what they need to do.
