I'm looking at the KK 18-24CBF tandem row disc to use with my MF-135
(7-1/2 ft wide, 860 lbs, 24 blades, 18" blade diameter, 3.0mm blade thickness, notched discs forward, plain discs in the rear row).

Anyout out there have experience with this particular attachment?

TSC wants $1171. Better price elsewhere?
