Those are all very cool, but I totally love the first one the best! I think you just have to be prepared to take any vintage electrical items to someone competent to have them checked out and probably rewired.
I vote for the first one, too! It's definitely the best!
Yes the first lamp is great but it is also £295!!You can buy it here if you're feeling flush right now - http://tinyurl.com/koeokc
