Plain ol' Bohning plastic jig.  Cheap & works just fine for the dozen or so a year I fletch.  I lay on a bit of wax on the clamp between arrows to avoid having glue build up.

I've got 2 Bitz's and a Jojan multifletcher. I bought my first Bitz probably 40 years ago and the 2nd one about 20 years ago when the magnet on the 1st starting getting weak. They did a great job for me. I then bought the multifletcher 6 or 8 years ago and haven't used the Bitz since. Either one is a quality product but I don't think the Jojan is sold anymore

I contacted jojan with a question when I was looking and they emailed me back saying they were no longer in business.
