Like you I am miles away from Sussex, grew up in Storrington so would probably go for one of the villages around that part of the county. Have always had a love of Amberley, some of my forefathers lived there, at the foot of the Downs I can't think of many nicer places to live.
Falmer, I'd soon be able to walk to matches and I'm an unsociable bastard so I wouldn't mix with the Nimbys anyway. I believe the area is of outstanding beauty as well.
