I don't agree w this statement soz. I think that in this crazy time we live in, EVERYTHING is a key! More than ever before for sure. It's just a matter of separating the boys from the men at this point. I'm a strong believer in sustainability, that's why I created this topic. ANYONE can pick hundreds of NEW keys and say: this is it.
But time and time we saw, that true keys are ones that stay and grow.
In that regard I agree with Kav, ASM300 will most DEFINITELY become an IH181 grail by 2040. Prolly before that time. But it's no fun buying a key for 300-500$ if u can buy a few for the same total amount and wait a little longer.
I cant go wrong with buying an established key when that book is asleep. I may not make money on it. But I won't lose on it. I did that with MP15, Star Wars 1, Tick and many other books when they weren't as hot as they are now. I also did it w less established keys and had good results but not as great. It's always safe when u have a budget set and u don't go overboard.
