I've had three FFs - all the regular Sport model and still have two
No problems and they have all been accurate, between +1.5 and +3.5 /day with no special resting position overnight
The long power reserve (120 hrs +) is great for obvious reasons, although the watch is a pleasure to wind
Blancpain is well-supported in Australia, with service centres in Melbourne and Sydney and my local AD is helpful (even purchasing their own strap-changing rig and changing customer straps/bracelets for free). Servicing is done by category and the costs are around the same as for Rolex. Only the Category 3 and above (high / grand complications need be returned to Switzerland). The US experience may be different.
Not really sure about resale... I imagine to figure on a drop of about 40%, possibly a bit better than other Blancpains. Obviously comparing any watch to a Rolex Submariner in regard to resale will be unfavourable.
Good luck : )
