Thanks for the replies everyone i appreciate it. I did not intend for it to seem as though money is my main priority, however as Mr Pig says i do have a fairly considerable student loan, which will increase further after ATC training.
I have done a fair bit of my own research and have discovered for myself many of the other factors which would influence my decision, its just the salary component has been pretty hard to find information on, hence the question.
Thanks for your help
