I think Scroggs' view is a little over the top. A type rating does indicate to the airline that you at least have the intellect/capability to get through a course that they are going to have to bet £30K that you can do. I think the more important consideration is Autofly's point that as soon as you get your 737 rating, you will get picked up by someone flying 320s or Emb 145s. Is it wasted money? Its your call.
