I'll take my chances trying to get it In Stock or through somewhere reliable for preorder, I don't like eBay preorders, too shady for this kind of money.
H-K Apestore or w/e their called are pretty reliable. I get all my obscure orders like this through them and are usually the first ones to send them out and keep good track of who bought one, have good communication etc.
Not common on ebay HK superstores so I have faith in them.
At the moment, ebay is the only place, we'll have to wait and see if other e-tailors like Store-Rooms or Toys2 carry it.
Also sometimes they really are limited to 100, sometimes it seems like they do a few hundred, I think it depends on what kind of preoreders they get but who knows.
