Sorry mate but I think if you do that you'll find yourself tens of thousands of £ down, still unable to find employment and now restricted to only one aircraft type. Only pay for a type rating if you have a dead cert guaranteed job at the end of it. If you take a punt on a SSTR hoping that a job will appear at the end of it, I think you'll almost certainly lose your bet. Sorry to be the bearer of bad news but the employment market is dead right now. Its brutal out there.
