Matt,
OAA do 130 hours of training in Goodyear, Arizona on their integrated course and a 28 hour Modular CPL course as well. All of their aircraft, including all PA-28s have Garmin 1000 GPS. They don't have any Glass Twinstars, but once MPL fleshes out, I bet they will get them for the non-MPL students. MPL will not include any twin flying in real airplanes, so it would be foolish for OAA to replace their Seneca's right now, as they might be selling off many of the twins in a year or two. I have to admit though, it would be nice to do the IR in a glass cockpit with an autopilot!
