Guernsey
As far as I'm aware, the recently advertised job in Guernsey got no takers, but this was for more than operational reasons -
house prices on Guernsey are very expensive, including for renting property. You also have the issue of residency - though it'll probably be the case that you'll get right of residency with the job, however if you lose the job you lose the right to stay on the island. Linked into that the cost of living (petrol, utilities, food) is also more expensive than in Mainland UK.
As for the unit itself, yes it's non-NATS, but they are radar equipped. Guernsey provides a radar service to all aircraft inbound to Guernsey when the have been handed over from Jersey Zone, and to all aircraft inbound to Alderney
As there were no takers for the position, they may consider a trainee; the channel islands have always had a good trainee scheme in the past, as most of the controllers are 'home grown', but where this resource 'dries up' then vacancies are advertised for personnel to come in from outside the islands.
That's all I can add, except that if you are interested then contact them and you never know how far you could get.
Good luck
