WW - Maybe I can help a little.
When I first started flying again two years ago it wasn't uncommon to meet guys who were hired at COEX, Chatauqua, Corpex, etc. at 500+ hours. At the same time Mountain Air Cargo, Mid-Atlantic Freight, and Ram Air wanted 135 mins for an interview. Mountain Air Cargo and Mid-Atlantic paid quite a bit more for new FOs though (Ram Air maxed at $95 per day/run then, I think). Some guys I talked to said they were going to these companies instead of the regionals because of the starting pay, because of the locations (local), and because some couldn't get an interview with COEX, ACA, etc. Mid-Atlantic and MAC also had quite a few 'lifers' who were never gonna' move on. Some guys just don't aspire to spiffy airline uniforms and much higher pay potential, willing to trade off for better quality of life and a known quantity.
On the other side ... the management types at Ram Air and MAC told me they were lucky to get eight or nine months out of a pilot before they were off to a regional with their new 200 hours of multi. It was a horror story according to the ADO at Ram Air. So today though, most of those 500-hour regional pilots are furloughed (or terminated at Chatauqua), so I'm not sure what the smarter move would have been if I had been ready then.
