The older you get without establishing yourself as a boss or in a supervisory position, the more likely you are to be run out of a company (IMHO). Youger guys come in and if they can gun for the older guys w/o repercussion eventually it works in one way or another.

I feel ya on this, but I've had several used purchases turn into surprises with issues that weren't disclosed and made me wish I had just bought NIB. I know buying used is smart financially, but it's not always best for the feeling you should be getting when getting a new pin in your collection. Plus the consideration of travel time to pick up a used pin, the potential hassle, unknowns, etc. Not crapping on your advice, just adding that this is not always black and white.
