Slepschy,
Taking the distance learning course would mean coming over here for the exams if you were to join bristol or any of the other distance learning courses. Most people I know who have sat their ATPL's have used Bristol, however I am different and have chosen London Metropolitan University, which is based next to the Tower of London.

Prices are almost identical for most courses and as ever most people will have their own views, but I find London Met very good.
Good luck mate
