I have to agree these Mondo posters are way too hard to get.  I have tried on several of them and if you show up 5 minutes after they go on sale they are gone.  I would love to see some reprints of thier posters just to give us geeks without deep pockets and unlimited time to get some.

I don't collect these but it's a similar thing with some Sideshow collectables, you have to be at your computer at a certain time to assure yourself of the item going on sale. I actually love how this works, there's a bit of a rush and anticipation. It's all part of the thrill of collecting

Then if you fail there's e-bay and the free market at work. I've had to resort to that many times myself and have paid 7 times the original price in the worst case and retail price on the rare occasion

If everybody could have one the item would loose some of its allure

They are indeed very nice.  Since they're nigh impossible to get, I make do with using them as screen savers at work.
