Strafer,
South Aer are the only school/club that I'm aware of at Cork. Certainly they are the biggest.
They operate Cessna's I believe.
They have a good reputation, although the only person I know who went there, wasn't too impressed.
There is another airfield in Rathcoole 13nm west of Mallow. It's operated by Rathfoole Flying Group Ltd (as I see from my Poolies guide!) Maybe they can help you with something more to your liking? There ph number is +353-22-22344
Sorry I can't be more helpful.
