Digital BW, The Print

The $150.00 Piezography Plug-In interests me.

Does this come in a CD format, or is there printed text information as well?

Does it require experimentation for best results?

Does it have a steep learning curve?

I'm vaguely aware of the controversy surrounding Jon Cone, etc.  Will this
effect my use of the software?

Many thanks in advance...
