steelbooks collectors holy grail question

[Twisted]

I'm more or less a newbie when it comes to steelbook collecting..i see how mirrors edge was difficult to obtain and has amassed a "cult status" following...just wondering if besides mirror's edge..are there other steelbooks that get people to go bonkers...or are just as hard to obtain?...i've heard a lot of hype for mirror's edge..and a lot of speculators out there..who buy a certain steelbook..believe it would be the next big thing and it really is'nt..one example i can site is uncharted 3 italian steelbook...not too hard to obtain...not very expensive..but was initially hyped for it being italian exclusive and one retailer exclusive..and people talked about shortages..all of a sudden resellers on ebay had dozens a few months later..and were selling around 25 euros a piece..so if anybody can name or show pics of steelbooks right up there with mirrors edge,.i would love to hear or see them!..thanks.
