Powrtouch Evolution Auto - Any deals around?

After three years of caravanning I have finally chose to have a motormover fitted - primarily for our storage site which is tight and on an angle. Having read reviews I am minded to buy a Powrtouch Evolution Auto Single Axle. I would like it fitted and all the sites I have visited seem to come up with same price! £1075. Does anyone know of any better prices or offers? Many thanks!
