Your local Wally World Sporting goods manager would probably be more than happy to order one of the NEF single shots for you. My brother has one in the new .17 HMR caliber and it is pretty good. The one he has came with a Bull Barrel though so you may want to check that out if that is what you decide to go with. Check with a local Gunshop or Gunsmith as they would probably be willing to order one for you as well. Wally World will probably get you the best price because of their volume but since the NEF product is inexpesive to begin with, that should not be a major concern. Check them out before you decide because many of the NEF guns have interchangeable barrels available for the same action. This would give you the option of up-grading to another caliber as the young ladies get a little older.
