I use the Bitzenberger. I heard that JOJAN makes a good one. If you only ever plan to fletch the Blazers, you can go with the Blazer fletcher, but you are limiting yourself only to the Blazers. If you want to fletch FLUFLUs or the traditional 4", go with the Bitz or JOJAN.
I've had a jo-jan for over 20 years.It's simple and does a decent job.Recently I picked up a new Arizona ez-fletch,designed especially for putting a good helical on blazers.It doesn't really offer any flexibility but for fletching a bunch of blazers in a hurry,it's tough to beat.
I only used a Bitz. I see no reason ever to try anything else! The Bitz will allow me to fletch anything, including bolts for Xbows. See what your friends are using and ask them to let you fletch a few arrows. Maybe a nearby shop will let you do this as well.
