Sean I am willing to remove the ballast, and keep the ballast for myself and ship the fixture making it lighter and cheaper to ship...it has a pretty fairly easy to mount...since the ballast itself is secured by a metal strip and the top housing holding it together with 2 screws which is a typical mounting for this fixture and it's smaller brother....So if you have a square ballast then I would think you would be fine....
I can leave the terminal box where you connect wires there (I know European style is different, but I wouldn't think it's a bad thing to use that one....so it can be as American as possible :-P)
