For grafted apples, St Lawrance, Cummins, Adams County Nursery, Fedco, Boyer and lots of others to choose from. . Lots of nurseries to choose from. Less important where the nursery is located than whether they ship you good trees.
I have been happy with the trees I get from Cummins and like their wide selection of apple varieties and rootstocks.
