Year One do not make parts. They are just a retail outlet. Most likely these hoods are the ones made by Goodmark Industries
http://www.goodmarkindustries.com/ On that web site they are listed as $500 for the hood and $130 for the scoop inserts. I have no idea if the quality is any good or not as I have not seen one.
I have heard of good used hoods going for about $400 but they are not easy to find.
