Find it hard to believe that it's a good starting salary in general or that it's a salary that matches the amount of work you put in? It is a good starting salary, I have never trained in it nor do I know anyone who does, so you may well have a good point there.
I guess it depends how quickly you advance through the salary increments too. If you only have to spend a year or two on that grade before oyu move up, I don't think I would be that bothered by it if it was me. If I was stuck on that for another 5/6 years, then yeah, it probably isn't so great.
