Carbureator for sale

Hi all,
Last year I bought a carb from National Carburetors. it has less than 10 hours of operational time. (http://www.nationalcarburetors.com/marine/fourbarrelholley.aspx)

This year I blew the motor, so the carb needs to go. If you were to order it from National its $319.
I'll sell this one for is $ 150.00. Including shipping, which will cost me about $50. I need the cash if I'm going to get a new boat.
