MKS Ezy removable pedals are strong, fairly light, and gorgeously well finished aluminum. The superiors don't need retention clips.

I have a pair of MKS Ezy MTE on my Dahon Mu SL, and a pair of MKS Ezy superior Esprit on my Bike Friday Pocket Llama. The superior is indeed a step up, not needing retention clips is easier to deal with, and the connection is very secure. But both pedals are far superior to any of the plastic folding pieces of junk many folding bicycles come with.
