Just a note that if you want to create PCB Panels yourself and save a bit of money, I suggest you load GerbMerge (http://claymore.engineer.gvsu.edu/~steriana/Python/gerbmerge/) somewhere and use it. It takes std Gerber files as input and will panelize multiple designs. I can vouch that it works well. If you do use it, I would set the design spacing to 4mil or so and ask the PCB house to do a 'V-groove" on the cut lines. It makes for easy separation. As well, if you do decide to have assmebly done, you can pay for 1 stencil instead of multiple. Here's an example: http://www.jbrain.com/2009/07/15/rom-el-test-boards/ In this one, I tried something different with the breakaways, but I would recommend V-grooves over the idea this picture shows.
