GRJ, that SEEED pricing is quite good! I'd have to go back and look but I think you posted that one of the later PCB designs at OSHPark was $13 and something for 3. That is a big reduction, 30 PCBs for $13. I doubt that I will ever be needing that many, but it's good to know anyway.
The Asian ones I got were about the size of your lighting boards in the pic above. I think it was the small DC-DC regulators. I can see where combining the PCBs like that would make things much easier to create and populate.
Soldering iron is sitting in it's stand idling and ready to go! Now, I just have to figure out how to set them up after making them...I think Adrian or maybe it was you posted something earlier about that. Maybe a thread re-read is in order soon.
