What are your thoughts on Collector Editions?

[Xombito]

I'm talking about shelf space hogging ones. Like the Dark Knight batpod statuette case or the Hellraiser Lament Configuration box set. Which is the only one I have (two if you can count the Blind Dead box set which comes in a nifty coffin box). What ones do you think is cool? What do you want Collector Editions to have? Are they lame altogether? Games apply to this too.
