Late to reading this topic. I have links in my bookmark collection for some different kickstands. Plush Bicycles carries the Color Plus kickstand in addition to some other varieties. I don't know if they will ship to the USA, though. Multi-S makes a kickstand that I think (in silver) would probably fit the look of the Brompton even better. Cyclopedia carries it. I know that they sell to the USA because they have an eBay store. They don't have the kickstand listed, but you may be able to get them to list one for you, or sell direct. As an aside, I've never found a website for Colorplus although they make quite a few parts. They do have a Flickr page if you want to check out what they make and see closer photos of the kickstand.
