Has anyone ever used one of the Gateway Feather Choppers. It looks pretty interesting. I was thinking about getting one since I like to use 4" shield cut feathers and those sometimes are hard to come by at a decent price. But I can find lots of full length feathers all over the place. And at $30 I think it might be well worth it. Let me know if anyone has used this and what your opinions of it are. http://www.gatewayfeathers.com/accessories.htm
