Nice! When I was a kid I used to love Lego, and I think I even built some Star Wars inspired things like an X-wing sometime.
If I had seen that Lego Falcon back then I probably would've wanted it more than anything! Actually I'd love to have one on the wall like that guy, if they weren't so expensive.
So what would all those needed parts cost? £600-700 like you said? That's still a lot!
