LRTT have a well-deserved reputation of looking after students who buy their courses when exam time comes round, so they would be a contender for your business, perhaps.
And they will set exams based on what they teach, so whether or not their material is up-to-date is not an issue. Of course, that should apply to any Part 147-approved Basic Training provider; the trick is to study and take the exams at the same establishment.
But LRTT is uniquely helpful to its own students taking their exams.
