Question about GPM Bismarck

Does anyone know if there was an upgrade done by GPM on their 1:200 Bismarck between 2006 and 2011? I have the chance to buy a 2006 version (with extra Laser Cut Frames) at a good price, but I don't want to get a kit that's way off the mark.

I know the 2011 version is pretty good - a friend built one.

Cheers, Danny
