So just to get away from the stock issue talk.
I actually started building mine last night, I never had 10179 and have never even seen one, so the size of this thing astounds me. I'm building it on a 6 seat kitchen table and I'm still short of room. Luckily most of the build is modular so far, so I can put the main model to one side while building then add it to the frame when all pieces have been used up. I know that some are hard-core and want to build this opening and sorting all bags at once but I can't imagine the scale of workspace you'd need to do that.
I'm around 1/3 of the way through the build and got through ep IV,V,VI in the background while building.
Only annoyance so far is the stickers, why oh why could they not have printed them. Especially the large ones supposed to represent the corridors which are difficult to place and adjust.
Yeah £650 is a hell of a lot of money for a retail Lego set, but I don't regret it for one second and those who are struggling to get hold of one, don't give up, it's worth the wait.
