Lucky141, an Italian blenderer, has put together a tutorial on using bevels to build spun shapes. The neat part is you can build the shape in 3D, not just as a profile, interactively. Way cool. Find it here. (Downloads a zip file with the english and italian versions of the tutorial.)
That, my friends, is a beveled circle! Takes about a minute to build, and another minute to tweak into brandy snifter perfection. This is an outstanding technique.
