You guys are missing the point. These things are not cheap. Each piece Sideshow puts out costs a few hundred each. Overtime, one person may spend a few thousand on these collectables. I don't know about you, but personally I don't want to invest thousands into products which have no value and are basically worthless. No, I'm not expecting to get rich by investing in collectables, but it would be nice to at least break even if I ever decide to sell up and get out of the hobby. Even if I do make a loss by selling, I'd want to minimize this as much as possible. Having an open edition size for a product takes away the value of it, and if you do decide to sell it one day you'd struggle to even get half of your money back.
Also, people choose Sideshow and Hot Toys for their collectables simply because they sell what people want and have so many licences, so it doesn't leave collectors with much choice. As an example, up until recently, if you wanted high end collectables of The Dark Knight trilogy, you had to buy from Hot Toys, so it kind of leaves collectors with little choice. I'm sure if other companies were offering high end products from these licences then people would look elsewhere. Other than Cinemaquette though, who else offers true high end collectables that are rare and high quality? Not to mention that Cinmaquette are in a much higher price bracket, have hardly any licences so collectors have very limited choices. If you want a product that Cinemaquette don't offer, then what? Not to mention all of Cinemaquette's human statues have very poor likeness to the actors. Sure, the quality may be great, but if it looks nothing like the actor what's the point? I only like their non-human statues, but as stated, they are much more expensive.
