I can highly recommend eBay seller "greengirl613" for NOS/VOS tubes. The prices are good, and I have rolled a dozen or so tubes from her with zero issues.
I have also bought a couple of NOS tubes from seller "BNBtubes" with no issues but it seems now that they are carrying more new production tubes lately.
