Wow... My last board was 10mil traces at 8mil spacing. Power usually
starts at 30mils. Anyone with a decent photoplotter should be able to
do that easily.

As for the plotting thing. I spent the whole weekend playing with
pens in my Roland DXY-1100. A Steadler Draughting pen (0.25) with
indian ink instead of the normal stuff does very well indeed You do
get the same type of pen in a refillable version intended to be used
in plotters, which eliminates the need for modifications. One thing I
noticed is that heating the board slightly helps.
