Shed,
got my ticket at Sheffield. Though, they might not be the cheapest, they certainly have an excellent reputation.
Ron and Eric Morris have been in business for quite a while now and certainly know there stuff.
True, the course might not be easy, but that does distinquish them from some of the other schools. If you got through the course the FAA exam is a breeze.
For my part I can only encourage Sheffield.
Cheers
