Cabair used to have an FAA instructor, based at Blackbushe
Mike is still around and also flies out of Fairoaks. I did my BFR and HP checkout with him there in January. I have his contact details if anybody wants to PM me.
There's another one in the west London area too just setting up for FAA work - web site
here. John did my conversion training for the SR20 and 22 and is always good to fly with.
