I know conversations can run long, but did you buy something from him after the long conversation, or order something that better suited your needs? Or did you just learn something from the discussion.
Seriously though he is the local LR expert and he is a friend of mine.
Being local I benefit from seeing him in person, conversations may run long, but he always takes care of me when I need a part on short notice.
At any rate, just trying to help you be green.
