do a search here on "Ormond Beach", "Naples air centre", "European Flight Training" and "Orlando flight training". Then get make a full pot of coffee and sit back for a good few hours of reading.
As for which one is the best, that is a never ending question. I'm sure they all have their good and bad points. Personally I've changed my mind about 6 times over which one I will choose (that's not including all the options in Europe that I've looked at either!).
Good luck

EDIT - but remember you can't do a JAA IR in USA, you have to convert the american one over here.
