Homebrew PCBs

I have tried moving the graphic images from the express pcb program into several other graphic programs. The scaling seems to be different between them and I usually ended up with a top pattern that didn't match the bottom pattern. The only way I have found to be accurate is that I use the DXF output for my top silk screen layer, I invert it in a cad program. Unfortunately the DXF output will not output the top copper layer. 

I gave up and now use the free pcb programs from Eagle or DipTrace for double sided boards. Both have the ability to print any layer. I think the libraries in either are a pain to use, and end up making most of my own components.
