No fog up here, its a long way from London :-)
As interesting as the Behringer units are, I'll be sticking with the Mackie for the time being. I like what it does, I generally like how it sounds (some slightly better reverbs would be nice), I like the interface and I like that it is reliable. If anything I would look at the Behringer kit for a second system should the need arise for more channels, etc.
Good luck to those who do sell up and move across, I'll be interested to see how they perform.
