No need to be 'sorry' - I agree with all you say (and am not looking to go the cheap route).
Unfortunately hard wiring is simply not an option in this property, so just looking for any specific equipment experiences anyone has had.
Your initial comment/link also most helpful and already noted.
Will probably be able to re-equip the furthest point with N ready new equipment (my understanding is that all the N boxes are backwards compatable to earlier euipment but obviously would check before buying).
Thanks
