Most showline breeders have long stock coats pop up in litters now and then. Find a good breeder(and don't keep yourself limited to Long Island) then look at the coat length that they have produced in the past, most often 1 or 2 coaties are normal in a litter.
Better to go with a good breeder that isn't really close to you than one that may not be producing a pup you'd be willing to live with for the next decade.
