I was just there a from 9/11 thru 9/14. I was there for a pa31, and only spent one day with someone that knows that plane. There were two gentlemen there for the twin cessna, and almost left the first day. Most of the training is on your own in front of a vcr and a computer watching cheesey videos and taking tests. They have 2 generic AST300 sims that are pretty beat up, a twin cessna sim, a baron sim, a 1900 sim that is nice, and two others but not sure which planes they represent. As far as the instructors go, I had one that had 300hrs, and was still working on his MEI, two that didn't seem to know s@#t from shinola, and one that seemed to have a clue. My guess is that very few of the instructors really well trained for type specific training. IMHO
Hope that helps you
