Found this for $75.00... previously ordered some disks with shanks to build my own hiller/bedder from Agrisupply and now this week... I got a head start on my project for only $75. AWESOME! I'll be cutting and welding soon.
I really like that setup with the adjustable gangs. The old school adjusting mechanisms are sweet - no need to carry wrenches. If you can replace the discs and any bearings that aren't spinning freely it looks like you could be hilling in no time.
