More info from Chris:

"Thanks again to everyone for their patience.

To finalize all of the pricing, we must first engrave one in each available grade of engraving. That is being finished now, and we will have pricing on all grades in the next few weeks (in advance of the shows.)

The target price for the first grade is just under 20K.

The 89 costs a little more than the 88, but it also comes with more standard features than the 88.
