There are some good modular schools in the UK, which have high standard, and it's not one of the top 2 expensive ones.
At the current climate of the Pound vs US Dollar, I can't see much savings in going to the US at the moment, as you still need to come back and also do the conversion. Maybe 10 years ago, when the exchange rate was 1 : 2 it was better.
If you do well, and you are under 30, I have not heard of anybody not having a chance with RyanAir, I would however be careful with some schools around in Europe, as I have seen pilots come from them, trained with them, and they have not all been trained to the same standard as you see in the UK.
