Last month I was quoted $16,200 for a BX22 with a 60 inch MMM.
Ended up buying a B2910...I was worried a bit about the size of the 2910, but it works fine on the Acre plus of grass I have to cut on a total of 3.7 acres. I got the rear mounted finish mower and pretended to cut the grass today...been real dry and the grass won't grow!
I don't think there was a rebate on the BX22 when the above quote was made. I have no regrets about going bigger, but it does cost more $$$
