Good luck, if this forum is a bit dry for Lego try bricksetforum.com, a lot of trades go on there and 100% lego focused, big contingent of SW Lego fans there as well.
Bricklink might have some for sale as well?
Have you tried Gumtree Ed? Its very popular for Lego - http://www.gumtree.com/search?q=lego+star+wars&search_location=United+Kingdom&category=all&search_scope=title
Not much doing here I guess. Even on Bricklink the cheapest is £185 loose and that doesn't include the shipping - http://www.bricklink.com/search.asp?pg=1&q=Chrome+c%2D3po&sz=10&searchSort=P
The Evilbay prices are even worse , might need to stretch the budget a bit.
You're going to have to post images, even if it is just of the bags? Are you planning to open them up?
The price for all three seems very good.
Enjoy them you will
They are all fully sealed and I intend to keep them that way. I have a loose Vader and Stormtrooper, but would like a complete run of the bagged exclusives.
Also on the wants list is a loose C3PO.... but that can wait :lol:
