Ok, I bought it. I haven't had time to fly it, but I must say that I'm disappointed with the cockpit. Honestly, Tim "Piglet" Conrad's T-28 Cockpit is far superior. Yes, I have the one that NorCal hacked and made "FSX compatible". It's far from perfect and I had to do panel and cfg file work and add some gauges in order to make it reasonably nice for FSX. Hey, I'm desparate for a FSX T-28 and desparate men will do some desparate things.
The only clickable features in the Alphasim offering are on the main panel and the throttle quadrant. None of the electrical systems or radios on the right panel are clickable, it's just a photograph laid over the model. Same goes for the trim wheels on the left panel. Tim's cockpit is fully clickable and functional, I just have not been able to iron out the night lighting issues.
Here are some comparison screen shots.

In short, I really wish Tim or someone would make a true, FSX T-28. The Alphasim offering is little more than port over of the FS2004 version with the bugs worked out.
Oh, I think the Alphasim sound set does not do justice to the T-28, the freeware sets for Tim's T-28 are far better.
