I just received 10 PCBs that I ordered from dirtypcbs.com a couple of weeks ago. I have to say that the quality is amazing. For $14, they are not dirty at all! They lack gold-plated pads, unlike PCBs from OSHpark, but if that is none of your concerns, then it’s a go! I don’t claim that OSHpark is obsolete now, but for simple prototyping, when you want to be allowed to make mistakes, dirtypcbs are filthy enough to allow you to do that.
