Sun Air is good I was there for a year from September 2013 to September 2014. The the people are very helpful; maintenance are very hard working and will repair any small problem. The most important thing is for you as pilot to report to maintenance any slight issue that you see unusual and they will always decide the best way out. Usually it would result in swapping airplanes so the one goes to the shop. This way problems are nipped in the bud.
Their training is excellent and you will fly in weather 200-1/2 with confidence. Good for your career.
