Mikey,
My research says the exact same thing about the cost of the dies, somewhere in the $350 to $400 range, depending upon the size of the dies. There were a couple of suppliers I found on the net listing the dies separately.
One company also had a manual tube bender for around $375 (I can find the link if you want). However as soon as you added in the hydraulic option, it jumped to almost $1,000. So as far as that goes, the BCR bender is a deal with the hydraulic bending.
I'll just have to fab a couple cages and exhaust systems for my buddies to offset the cost of the dies.
Cheers,
Doug
