I know someone who bought on scotland island, and got sick of the constant car break ins at the ferry carpark. I think the residents eventually all contributed to a permanent security guard.
I have friends who live at dangar and have visited a few times. Personally I think it's a beautiful spot. I think sometimes carrying shopping at night in the rain from the boat to the house ain't that idyllic but for the most part they love the lifestyle and don't mind the commute too much.
