I've got a pro-tools heavy duty (5/8" arms and not 1/2" arms) with a 240 degree 1-3/4 OD tubing die which allows for complete 180 degree bends.
This is the mac daddy of manual benders. It comes complete with the stand and degree ring. Bolt this thing to the floor and start bending.
$600 plus shipping (this die alone is over $250)
The heavy duty bender setup new from pro-tools is $750 plus shipping, and that price doesn't include the 240 degree die.
This thing is heavy and shipping will not be inexpensive.
