Dorkin' in York is legacy video and really is the history of BMX. Both street, dirt, vert, and a good deal of flatland are in the videos. This is the work of Mark Eaton and basically created some of the gold standards for which videos were to be produced in the future.
As for Flatland Fuel... Absolutely the best place to order stuff from if you need what they have. Pat is awesome and you are dealing with a rider, not a clueless corporation. He'll work with you to get you what you need as well.
