I think it's safe to say that nearly every B1 you come across, whether mine or others, you will not see again, or it will be years before you do. The exceptions are few, but they happen, such as the glut of B1s for The Dark Knight or Melancholia that occurred in the last few years. But not many.
One of the B1's that's still with me is for No Country for Old Men. I have never seen another one since. If it came up for auction now, it could go for $50 or $500 or $1000 on any given day, depending on whether the right people where there. I know there are a few out there that would pay over $1000 for it. And there's a few that wouldn't pay more than $50. Do you take the risk it won't come up again, waiting for the lower price? No fucking way.
I've only been burned a few times. I paid hundreds for Melancholia B1's when they turned out to be as common as Thierry's bullshit. But, for each one of those, there are 200 at least that did not show up again.
So, the time to buy is when you have the chance. Wimps need not apply.
