I know you think that Speedplays are expensive, but I paid $110 for my Light Action Speedplay pedals. I really like them because they have good float, are completely rebuildable and are very easy to get in and out of. Just step down and and you will hear a click. You can even ride them with regular shoes, because they are flat and double sided.

The most popular road pedals are Look, the Shimano's Look imitation pedals and Speedplays. I haven't tried the Crank Brother pedals. I think they are really more of a mountain bike pedal which works on a mountain bike shoe.
