If I might give you my 2 cents: while I appreciate that cost is very sensitive to everybody who wants to train as a pilot, the cheapest option is rarely the best. And that's something you can apply to more than just aviation! If you plan on flying in Europe then train in Europe. If you plan on flying in America then train there etc... While learning to fly in Ireland my be hindered by occasional bad weather, Irelands wind and rain will make you a far better pilot when compared to someone who only knows sunshine and a gentle breeze. You will gain far more experience even though you end up with the same number of hours!
