Put about 1500 acres on an 8 meter last fall. Very happy with the machine. Rented a joker to compare as well as demoed a landoll. The protill is like you said is way out of my price range, plus its the same unit just heavier. Not sure if the extra weight is needed or wanted.
Did a mix of everything. Heavy straw stubble/flat on the ground, rocks, sloughs, peat.
Originally ordered with all smooth. Wasn't 100% happy so I had a pallet of notched delivered. Did a test with switching front only to notched then the whole machine. To me that is the way to go. Although I talked to them and Gaber industries at the red deer show and would like to hear more about the self sharpening wavy disc.
Also originally had the large rubber packers but for my soil and what I'm trying to accomplish I wanted the baskets and had that changed. If you plan on doing spring work and need firmer soil than rubber packers might be better.
There are a few small issues but Precision is really good to work with and are constantly improving the design. Can't beat the practically lifetime bearing warranty...
