Greenlee/Texron has one that we've been using (for apprenticeship classes) for many years. It's probably 10 years old and is hosted by Wayne Lundquist and covers handbenders, ratchet banders and all the way thru the hi tech digital electronic stuff. It's done in segments so you can pick and choose which to show.
If you can't get it from Greenlee contact me and I'll make you a copy.

Ideal also has one but it's not as good. I can make you a copy of that also.
The Jack Benfield video is about 20 years old but acurate and kinda humerous. It's available from EC&M bookstore but I'm not allowed to copy that ... sorry copyright stuff.
