Can't negative the Jets... If I remember correctly, they have a quick release which would appeal to me and I also believe they are a few shekels less than the Bessey's.
Unfortunately finding replacement dentures for a lame duck are easier to find here in Aussieland than the Jet.
Do they have the serrations on the side/wraparound like the Bessey?
If your first cut is too short... Take the second cut from the longer end... LBD
