Anyone have any experience with the King Kutter 3 pt disk? I'm in the market for a bigger set of disks and have looked at these at TSC and wondered if they would work well and last. I currently have about 6 acres to plant and I need something bigger than my small pull behind one now. I have a late 60's AC 170 which has around 55 HP so it would handle this implement. I may also look around at some farm auctions but I'm always leery about buying used equipment.

I think our local TSC wanted a little less than $1200 last summer for the 7.5 ft model. Here's a pic:
