You should seriously consider the Fermanagh flight centre for your training. I know the drive might seem a bit much from Dublin but I'm currently doing it there and driving from the east coast and think its well worth the effort.
As Irish Seaplane stated in his post, there are no politics or agro, the standard of instruction is top quality and the aircraft is in prestine condition.
One huge advantage of flying with them is the transparency and lack of hidden extras so your can be assured of no nasty surprises !!!
Please pm me if you need anymore information.
