lol... I only know the price of mine... it was $1020 delivered. There was a dealer in Montgomery who had an angled 6' unit (not industrial) and I believe they wanted $700 for it... but don't hold me to that figure, my memory is thin.
I have now added 3 before and 3 after pics to the duragrader page I built that shows my sister-in-law's driveway that I did. They really only had dirt and grass with potholes... very little gravel or rock. It smoothed it out nicely but now I'd say they should get a load of rock to keep it from washing, especially on the hilly entrance. Also after it rains I can re-grade it and I believe it will be even better.
