I use 27mm all the time, it is the size for my lug nuts. There are many 6mm and 7mm interior fasteners on my vehicle so they get used too. I often use wrenches larger than 1" and 22mm as there is nice mix of metric and standard under my truck. As far as brands go I agree with what much...
I am sure that Expedition Exchange ships internationally. I know both of the owners personally and they very nice and knowledgeable about everything they sell. Also, as you can see from the pictures, they are very particular about their tools.
