Lets try and be fair with regards to this argument. If you can afford OAT then why not however anyone who's outside that type of 'financial bracket' then they can go to the other (and in my opinion excellent) schools up and down the country. We all know what opinions we harbour personally but attempting to win over people from the other side will take forever.
For every OAT graduate that attempts to present him/herself as the creme de la creme of training should provoke others modular guys to offer an equally compelling counter argument to any potential employer. Don't let OAT's graduates stand on your heads in order to get forward themselves at your expense.
