Maybe do some research of your own?

And in full disclosure, I did try to buy a copy but didn't get one in the first wave and I missed the second. Like I'm sure many here, I'm buying what I can because i see a future in the HR era. So I have no beef if these are shilled. In normal circumstances I'd say probably, but people are paying thousands for even dumber SW spec, so I don't know what to believe anymore.
Normally I hate the exclusives, but I give them credit for their tactics. Why sell 3000/1000 copies for $15/$30 when you can just sell 600/600 for $80? If the 1st apps take off, you have the "One" to own for sure just due to rarity. And if you only sell 400 and keep most of the rest, you have a massive goldmine on your hands.
I know people comment about the whole 600/600 run being BS, but it doesn't really matter because the perception is out there that it's 600/600 and many newer collectors will never question it.
