The 912T is actually a pretty good. The problem with 9 series ball is that the covers dont match up to the core. The intermediate diff was too high causing the ball to flare heavily and bleed too much energy before the break. The covers could not keep up especially on the THS. So they burned up on the THS and went 600 ft in the oil. That is why the 912T and 916AT were the most popular because they were more usable. Lowered the inter diff, ball doesnt over flare, makes consumers happy to watch the hockey stick.
Even with the release of the 912T and watching the track vid of Mitch and Mike comparing it to the 716T, there was only 2 boards at the arrows of separation. Why spend high performance money when you can get close to the same hook for $30 less?
Beard, I think you're price is very fair. However, this is the new nature of the beast. Once the latest and greatest come out the previous becomes obsolete unless they are extremely popular. This wasnt exactly a popular release so in my opinion you'd be better just drilling it or storing it. My .02.
