Danny Ryder of Danny's Pro Performance in Keyport, New Jersey, was nice enough to fill our empty 10-pound bottle with the good stuff. All nitrous companies ship their nitrous systems with empty bottles for safety reasons and shipping regulations. Most speed shops will have nitrous filling stations on hand and will charge between $30 and $40 to fill a bottle. It is also a good idea to find out if the filling station you are using has a filter on it. This will ensure your nitrous is clean going into your new bottle.
