I've used them in the past and as much as I hate to say it, when Jerry O'Sullivan was there it was a top notch company. However, after he left there was a gradual decline in the company. It used to be they were always watching out for their contract pilots, however, as time went on they became more and more concerned with not pi**ing off the airline side.
I would think long and hard about using them again. For my money PARC is by far the best of the bunch. But, that's not saying much.
