I had a chance to play around with some CuCl2 (Cupric Chloride)
etching last Friday and performed a test etch with a small segment of
PCB created using the "cheap paper laser toner-transfer method".
The traces are 10 mil in width.
You can see check out some pics at

The neat thing about using CuCl2 is that the byproduct
of the etching process generates more CuCl2. And because of
this, the etchant solution can be used over and over.
I can't imagine why people are still using Ferric Chloride.
