May want to look directly at Wellgo's site.....there are a LOT of options/designs that look interesting, some in the road section, some in the BMX section, some in the city/touring section, platform pedals are scattered throughout the different sections.

Once you find one that looks interesting, you can Google search it's model number as 'welgo xxxx' to see who might sell it. I've found specific ones I'm interested in on eBay, Amazon, REI, several of the US centric web retailers, and then several of the European centric web retailers (these normally have many of the models in stock).
