Ted,
Just remember that Streamline are only in the business of making money out of their type ratings. They dangle that little carrot to the Wannabe of a possible job on completion. Do remember that it is supply and demand and they can use the type rating as their selection process as well, so if they were looking for some pilots who would they take? Direct entry applicants with much more experience than 250hrs and possibly experience on a turine, a 'type rater' who sails through the course or one who scrapes through? Not trying to judge your ability as I don't know you, but be aware that if you don't fall into the 'sail through the type rating' category you stand very little chance of even an interview. Judge for yourself, but don't go spending another £7k 'in hope', do it because you know it will get you where you want to be.
