I’m starting to use Upverter to realize cheaper project PCB’s. I’ve found Upverter easier to use than Eagle, but there are some quirks. It took me a while to figure out how to set a board outline (just set the dimensions). For simple stuff, the layout works pretty fast. If you have more than 30 components then bridging ground or VCC traces really starts to lag. I prototyped a board and had it sent out to 4pcb.com. I look forward to seeing how easy it will be to get the cheaper 5x5cm boards from Seeed Studio. I would love to see a concise summary of PCB design best-practices.
