A lot of people sell cheap brass cones. I have used cones that I had made for me by a local machine shop, and cones made by others. The best sounding cones I have used came from http://www.starsound.biz The quality of the brass is better and the geometry of the cones is better. Cheap brass cones discolor too fast, if that's an issue for you...
I replaced all the DIY cones a while ago and have not been disappointed. Starsound showed some new designs at the RMAF that may or may not be one the site already.
