George Kaye Small tube Tester

Does anyone know where one of these units can be purchased?
I would suggest you go to the Moscode link under "Manufacturers" here on the A-gon and contact George directly through the site links. Not sure if he still makes them, but he might.
If you can't find a George Kaye unit, below is a link that has a model that they say is better?
