The GR211 nixie tube socket PCBs that I designed have arrived! 

They came out excellent. I was worried for two reasons. The footprint for the GR211 and the SOT-23 transistors were untested. I created cusom libraries in Eagle to deal with the unusal transistor that I selected, which can handle up to 300V and for the tube. The tube took some figuring out because its datasheet has the footprint from bottom, rather than the top. I ended up screen grabbing the scanned datasheet and mirroring and flipping it as if it was viewed from the top, I could then create the footprint in eagle - which are traditionally viewed from the top.
