For those that don't know:

- Buying, well that one seems self-explanatory.

- Toner transfer, printing the circuit on a special paper and transferring
the image onto the PCB using heat and then etching.

- Inkjet, printing the circuit directly onto the PCB using etch-resistant
ink and then etching.

- Milling, using a CNC machine to carve out the spaces on the PCB to leave
the traces intact, no etching required (toxic dust).

- Photo, printing the circuit on a 'transparent' paper, placing it over a
PCB that has a photo-sensitive coating, then dipping it in a developping
solution and then etching.

Google has many tutorials explaining each technique in detail, except for
the Inkjet, and that's the technique the group is testing right now.
