I use ExpressPCB   http://www.expresspcb.com/   shareware and their
mini-board fabrication service for initial prototypes.

For larger quantities, I use TraxMaker to create Gerber files and
BareBonesPCB   https://www.barebonespcb.com/!BB1.asp   fabrication
service.

You can also get 2 oz plating (instead of standard 1 oz plating) from
Advanced Circuits    http://www.4pcb.com/index.htm   which helps high
current applications.

My graduate students prefer EagleCAD   http://www.cadsoft.de/
shareware for creating Gerber files.

It is very difficult to make high quality double-sided boards with 
plated-through
holes and 0.010 inch traces at home

If you are serious about selling boards, I strongly recommend that
you learn to use ExpressPCB.  It is very intuitive.  We make all of
our mechanical engineering students who take ME 462 Microprocessor
Interfacing   www.mne.psu/edu/sommer/me462   learn to use ExpressPCB
so that they can understand the fundamentals of designing boards
for commercial products.

You will never again think about etching your own boards.
