The manufacturer's product page is http://www.verotl.com/vero-wire. The site includes links for ordering direct and a list of distributors.
Formal verification of safety-critical software, software development, and electronic design and prototyping. See http://www.eschertech.com. Please do not ask for unpaid help via PM, use the forum.

Have used the solder soluble insulation magnet wire for many years.  Usually use #31 wire without comb strips (which take up extra space on the board).  It lays in place quite nicely on Vector 0.1 inch matrix fiberglass perf board.  If desired, the wire runs can be tied in place with sewing thread run through adjacent holes in the perfboard. I use copper adhesive tape (0.1- 0.15 inch wide) for power and ground bus. The solder soluble insulation wire is available from at least 3 wire manufacturers and a 1lb spool lasts for years of prototyping.

Some are having success printing etch resist directly onto blank PCBs.

Many Epson pigmented inks work, if you bake them. 3 minutes at 230C, the point where the copper just starts to turn color. There are a lot more details to it, just as toner transfer is more than just ironing a Laser print to a board.

A Yahoogroup I started about it:

Well, this post is a year old (I remember reading it the first time!) so I wonder how the state of CNC "etching" is coming along?  I saw PCB mill set up at the SF Maker Faire this year.  Want.  Want want want.

CNC PCB etching comes with its own set of problems.

I don't suppose you'd care to elaborate a tiny bit?  Give a brother a boost up the learning curve?

Copper swarf incompletely separated. Copper is rather soft. Make sure you use cobalt bits, as the fiberglass will wear out HSS bits -very- quickly.

Much more info on Homebrew_PCBs on Yahoogroups. Full disclosure: I'm listowner there. I started it because I saw a lot of information on making PCBs spread thin, dribs and drabs here and there.
