Up until now I've been ordering OSHPark quick turn proto boards because they're cheap for very low volume. For the initial Pants run I went with Elecrow in China from the good reviews I've heard. I put in the order last week for 50 Pants boards with 3 day shipping to the US.
DHL just notified me that I should expect them on Tuesday. But I'm totally unprepared. I don't have stencils, I'm missing some of the more expensive parts, I don't have a Tindie account set up yet, I haven't figured out shipping or packaging, I don't have a test jig built yet, and my bench is a mess! I don't know why, but I didn't expect 50 PCBs to be manufactured, shipped halfway across the world, and delivered in under 10 days!
