I've got a louvre set up. Used to run it in my 100 ton shop brake. Worked alright but was a little hard to handle because of the speed. Am in the process of building a portable frame for it. Something big enough to do a car hood in. Will run it with a air over hydraulic cylinder, pretty much the same as everyone else. Was punching 'em for a $1 each. Don't know the going rate but the price didn't seem to bother the individuals I've punched for.
