PCB forum, YouTube posts and other misc. info on the internet.

In consideration of all that, I concur that if you can justify $60 or so=20

(about $100) and give that method a try. I am using way too many Black=20
ink cartridges any way.  If I can repeat others success's, I will be=20

InkJet PCB will be a winner when they find a really good resist to print.

Unfortunately, small quantities of chemicals and other materials are=20
likely to be life limited. Not good for a casual user.

Direct print to the copper clad is OK if you are not going for fine=20

documented on the 'net.

Milling operations also have limited detail.
