I can get one for cheap (fire sale); the Dahon and Yeah web sites seem to indicate that the frames look almost identical. Componentry I accept will be lower, but for that price i don't care; however, if the frame is dodgy, then it's money wasted. I suppose I should have stated it clearly. The bike in question has a similar frame as the Dahon Helios P7.
