I've had a friend wanting it, signing up, and upon hearing the price went ape**** cos it was over 50 quid. Ha.
I'd like the open window edition. I personally would open orders, see how many pay a deposit while knowing full price, seeing the product (still no pics, this annoys me), all the jazz, and make enough to fill the orders and have for about 50 I'd say full figures for eventual replacement parts.
I don't see this line being very secondary market-y. Completionists being one thing, the second being, all collectors of Who are concentrated over a few places. It's not a character a lot of people would buy outside the fanbase, unlike Superman or Batman or Whoeverthe****elseman. So I don't think secondary market value/rarity have very much effect.
