Mike, can I please ask what program you use for designing your PCB's?

Sure, after actually buying a couple of VERY expensive programs and finding them WAAAAY too complex for most normal needs I use freepcb for almost everything these days.

I have all the addons and that allows the generation of picture files from the gerbers built right in so I can then import those pics into Corel Draw and invert them, print on tracing paper and make prototype boards - all within a couple of hors of dreaming up a project.

Actually I wouldn't bother with any other program these days as freepcb is just so good.

There is no autorouting BUT there is an online site where you can upload your files and it will route for you - personally I prefer to have control of that and so I manually route all my designs.
