[Onomea]

Don't know much about it myself, but I think a good start would be to get some background. R.L. Wilson's Steel Canvas , while it covers history and other makers as well, and not pricing, seems like a good start. Get an intro on the subject. Cheap, too. Probably has a bibliography as well.
