Why did you choose Dirty PCBs? Was there something else you liked about them? Adrian Jones over at WoodUino tried it out:
As you can see, I chose a white coating for the boards but they offer many colours at no extra cost. The plating is excellent and the boards soldered easily. The component silk-screen is clear but all over the place – my fault because I didn’t bother to take the time to pretty it up. The boards are clean and tidy and look very professional.
