How to purhcase a fully working HP41CX on eBay?

As far as the DSMX goes, what else can they do?

Mental disorders exist.
Each requires different treatment. (i.e., Bipolar Disorder requires different medications than straight depression or schizophrenia.)

There is no brain scan or PCR (generally) that can detect them.

So, you have to develop behavior based diagnosis methods.

Not to say that there is not a lot of fluff in the manuals, but the need for one is there.
