Are you looking to get road bike pedals or stick with mtn bike pedals? I have a set of Ritchey V.3 Pro Mtn. bike pedals that are GREAT! Better than the Shimano M515's (which seem to be the rage around here) AND they come with the SPD cleats - you don't have to buy them separately. Granted, you probably already have the cleats, but heck, consider it something for nothing... 
I got them at Nashbar for $49.95 (on sale).
And I know NOTHING of road bike pedals...
Good luck!
