The BPE Pro is less in cost. The scale for adjusting the nock aligner is marked out at 360 degrees and can be adjusted 1 degree at a time. I also like the forward arrow holders, they are circles to match your shaft diameter and hold the arrow better. These are just my opinions. I have made a couple hundred dozen arrows and doubt that I will ever purchase a Bitzenberger. I own 3 BPE and 1 Jo-Jan multi fletcher. I was given the Jo-Jan as a gift and do use it once in a while. But is isn' t precise enough for me to use on a regular basis. Take care..............Tom
