If you have 500 components, differential signals, and controlled impedance stuff that's a different story.
A handful of surface mount components can easily exceed 500! But like you, I find the idea of using an open source program much more attractive. Someone mentioned earlier about making PCBs on a milling machine. That needs a different approach than to etching. To reduce tool wear one should leave as much copper on the board as possible, removing only that which is essential to keep. Thinking of it logically, leaving as much copper on the board as possible will preserve the useful life of the etchant, but most people leave remove as much copper as possible, except for RF boards.
