If your not a in a rush, keep your eye out for used ones.
Dont think Hoppy has any for sale at the moment but you can always ask.
Amazon too.
All the bigger mail order places. They're now including it the sales. Although for the moment there may be situations where its doesn't apply. If they have no operation in the state, and your state revenuers haven't made it mandatory for you (yes us the buyers) to pay the difference.
