Of all the people I instructed with we went on to 737, A320, B200, S2000 and D328. And threw are still stuck instructing, one miles from home. The turbo prop fliers seem to have WAY WAY much more fun than the two of us on jets.
My advice would be take the first job you're offered. You never know what will happen in the industry so take what you can when you can.
It's a sad fact that few people these days seem to move up the ranks on to jets. You either get straight on to a jet or your stuck turbopropping for a long time. It's just the way it is unfortunately. However I much rather be on a TP than still instructing - there are only so many trial lessons you can do in a week! I often feel that I missed out by not getting any TP experience, but I wouldn't swap where I am today.
Take the job. You'll never look back.
