I'm probably in the minority here but I use Mavics. I was going to get some Look Keos, but the Mavics can be had for 75 bucks online, with a titanium spindle. They're super light and have a good sized platform. I have a set on my road bike and tri bike for less than I would've paid for the Looks. Been riding them for a year and >2500 miles and they are solid as ever.
Downside is that the cleats aren't compatible with, e.g., spinning bike pedals if you care about that. They're also pretty damn ugly (in my opinion), but I'm cheap so I went with them anyway.
