r10bbr, Stop just concentrating on the price! I would have thought you'd have learned that by now, after your experiences. It's the quality of instruction and - very, very important - how you get on with your instructor which count. Also the organisation at the school - whether you can fly with the same instructor all the time if you want to, whether you can book lessons when YOU want them, type of runways (grass only limits you to dry-ish weather), and a whole host of other things. All this can make a huge difference to the number of hours it'll take you, and more importantly, to your ability as a pilot at the end. Early instruction is very important; you don't want to re-learn stuff you've been badly taught - and, sadly, I speak from experience here. :-(
Look, I don't usually blow my own trumpet, but I'm an instructor and also an aviation writer. I had an article published long ago called "What School, Which Instructor" which covers all these issues and more. If you're serious about this, PM me your email address and I'll send you a copy. You might find it in back issues of Flight Training News, but it was published about 8 years ago!
All of this is equally important when it comes to choosing a school and instructor for more advanced courses too, such as CPL, FI etc, so don't think I'm treating you as a beginner. I'm simply trying to pass on the benefit of my experience. Plus...loads of people helped me on this site in the early days; it's time I passed it on.
