The only surfaces large enough for that at home is the coffee table or the dining table.
Neither of which are Lego friendly.
Think I'm going to get it as well... my favourite ship of all time plus the holy grail of lego sets - there is just no resisting that...
A little bit of a question remains about where to store/display it (as others have said above)... I really like the idea of putting it under the glass of a glass coffee table but I don't have room for a coffee table anywhere! I wonder how easy it would be to build some brackets that would allow it to be mounted to a wall safely?
