I have used the Bitzenburger jig on a few occasions and can vouch for it's quality and performance. In my opinion it is the best jig on the market. For my needs I decided to go with the Jo-Jan mono fletcher. It is available for about 1/2 the price of the Bitz. Like the Bitz, the Jo-Jan is also an all metal jig. The standard jig comes with a straight clamp that is adjustable for left or right offset and 0 - 2 degrees. Or, for the same price, you can buy their helical fletcher which comes with your choice of a left or right helical clamp capable of 11 degrees helical.

I've also used the Arizona EZ fletch and had no problems with it. It was easy to use. One big advantage this jig has is that you canapply all of your fletchings at once. Rather than 1 by1 like the Bitz and Jo-Jan.
