Well, My new impact wrench arrived. It's a DEWALT DCF899N and cost me £132 inc VAT from Howe Tools It didn't come with a battery/charger as I already have loads of dewalt ones that I use for work. I'm happy to say its just a bit brilliant! Ive just tried it on my Land Rover 27mm wheel nuts and on it's lowest torque setting it removed them with ease. Very impressed!
