I'll need to be laying out some boards for signal conditioning and I/O (optos,
relays, etc.) and I'd like them to have a professional look.  One offs for my
own consumption not for sale.

I've downloaded AutoTrax.  Nice program, but I don't think I can justify the
cost (after the free period) for the few boards I'd be doing.

Does anyone know of any layout tools available on the net that might be
suitable.  Possibly limited to x layers or y parts count?  I think I can live
with limiting it to double-sided possibly w/jumpers/cross connects.

For the few I'll be doing initially I'd expect to etch them myself and use my
(home conversion) CNC mill to drill them (I can use Ecelon <sp?> drilling
files).

I would like to also have the ability to send off drawing files, etc. to a
prototyping house if board complexity/quantity warrants.

For future use:  If you needed one or two boards made (possibly double sided at
most) what web resource would you use?

I can see how I would expose the boards using overheads printed on a laser
printer and photo-etch but how would one do the equivalent of silk-screening for
a home etched board?

Cheers,
