Actually, I just started my instrument rating at American Flyers this past Monday. I got my private at a Part 61 school in central PA while I finished up at Penn State, and I'm probably going to start my commercial back there as soon as my instrument is done.
Before I started, I did not want to go get any certificates or ratings at American Flyers. My parents actually wanted me to. So I gave in and started my IR there. After a week, I can say I am VERY impressed. I've structured it so I can go Monday through Thursday from 1 pm to 9 pm. A lot of hours, yes, but I've learned a lot. I work part-time for US Airways in State College, PA on weekends, so for the next 3 weeks or month or so, I'm commuting back to SCE on Friday mornings and back to Jersey (where my parents live) on Sunday nights, then commuting to American Flyers' Morristown, NJ location Mon-Thurs. each week.
I am doing my commercial in State College Part 61 because I will have probably close to 120 hours or so when my instrument is done in a few weeks, and it will probably just be more realistic to get the 250 hours and go Part 61 because of different time requirements.
However, in one week, I have been impressed enough with American Flyers to seriously consider going for my CFI course there after my commercial and multi-engine.
The programs American Flyers have are pretty pricey, but I give them a big approval in my book. Just be prepared to study and move fast.
In four days this week (totalling about 29 hours) I've gotten probably close to 13 simulator hours and 5 hours in a fairly new Skyhawk 172. The Frasca 131 simulator is very sensitive, but it makes the actual plane a heck of a lot easier.
If you have any questions, feel free to ask me. I'll be mroe than happy to answer. Good luck!
