Thanks very much idun and everyone else. As you say idun, a lot can be spent on net sites for the adverts. I've spent quite a few hundred, plus an inordinate amount of time and energy.
Hope to have time to make a decision on way forward by the end of the week/beg of next. Still no word from A about Sat morn's viewing. Don't feel very inclined to contact him until I've decided my way forward, which hopefully won't include him, and I shouldn't think there's any chance it went well or I would have heard by now!
