Acuba, you need to think of how many schools you're going to attend, 5 schools to get fATPL won't look good on your CV.
Ronnie, don't look at the prices, they're not the most important thing.. Have a look around the school you think of choosing, talk to ex students.. do a research, then choose few school which you best like and think it's the best for your training, then, from them all, choose the cheapest one.
I was going to go to Highland Flying School, because of their prices, I choosed Tayside instead, because it's much better in so many ways!
