Gas cylinders

Has anyone had experience with buying a cylinder and taking it to their LWS and having it swapped or filled? My local store said a 150cf tank is the largest bottle you can own and have swapped but they can only sell an 80cf bottle. Trying to find a way to avoid leasing bottles forever.
