It's been a few years for me, but...
RAF operates Lears, Bandits, C310/402s, Mu-2's, and I believe they have some Da-20's on property now.
In the Bandit we were on call 24/7 Mon thru Fri. One weekend you were on first call, the next weekend you were on second call (this sucked because you couldn't go do anything and you still might not fly which = no pay for your lost weekend). I remember it being a 45 minute call out, maybe it's changed.
It's a family owned and run business that's been around a long time. Bill Kostich (owner) pays cash for everything so I don't see them going out of business anytime soon.
The mx was average.
For an on-demand, p. 135 operator, they pay very well with great health bennies.
You will do a lot of flying. This was my first flying gig and I built a lot of time of quick. I think I averaged around 100-110 hours per month.
When I was there it was a pretty tight pilot group. We would often run in to each other a 5-6 am at Jerry's (greasy spoon) after dragging back in from an all-nighter. There were 2 or 3 bars on M-59 that we would meet up at on Friday nights.
Overall, I was treated fairly and my only regret is that I didn't stick it out longer there. I could have payed down a lot of debt but the shiny-regional-jet syndrome got the best of me

.
Edit:
I forgot to mention that most of their flying is for the automotive industry so the flying is tied to the same up and down cycles that the automakers experience.
