I'm currently working on my PPL at
Long Aviation (should be done in the next few weeks!). The instructors are good and the planes seem well cared for. I've been very happy here.
I've also heard good things about
www.flycarolina.com (though I suspect you'll spend a lot more money there).
One place to avoid would be Wilgrove Air Park. I trained there before moving to Long Aviation and left due to bad instructors and poorly maintained aircraft.
Best of luck to you!
Cheers,
Steve
