Hi. I'm trying to find an efficient aircraft. I've read and heard that posting here and asking for help is a wise thing to do ... so, I'm posting here and asking for help. My thanks in advance to anyone who is willing to give me some advice.    I'm seeking a plane generally for flights from the Central Valley of CA to LA and SF. This generally means:      one person in the aircraft. Rarely two. Three in the airplane is an unlikely possibility.       Usually approx. 200 miles
