I have considered this myself, however I am not prepared to do this at the moment as there are definetely some non-type rated people getting jobs at the moment without having to fund it themselves, albeit being bonded. In the Freight Dogs Forum it was suggested that people do get jobs with BAC but not immediately. I guess the risk you take is unecessariliy paying for the rating yourself. Start pay with BAC is quite poor too so it may be difficult to pay a big loan back.
Perhaps someone who has done this can comment?
