That's the problem, Steve, about the only way to get the time nowadays is at regionals. And, at regionals it is very hard to get PIC time, without which getting a corporate job is nigh impossible. You mention King Air jobs, well, they are mostly single pilot, so you need to have a record of command time. Good corporate jobs don't turnover very often and when they do, hiring is word of mouth. I just got off an airliner and got asked if I was interested in a job. I'm not, but I'm sure they are filled already.
Corporate is very good, but hard to break into. The regionals or the 135 guys like Ameriflight is for young kids who don't have a life but flying and can live out of car. Until I was 35 I didn't own anything that couldn't fit in a Ford Pinto--cheap and easy to move on.
