Here is a tool that we use at the early stages of our corporate aircraft acquisition searches:
Good suggestions on this thread.
The original poster did not explain much about his needs. What is his usual trip length? Cargo ever important? Usually full, or empty? If the Cirrus is working for them, but they need more room, comfort and range, why not throw a executive configured Cessna Caravan into consideration? Without the cargo pod the short fuselage aircraft is a 175 to 190 knot machine and it will carry a Phenom inside (almost).
If I needed to go fast for that price, I'd grab one of the last Sabre 65's built and zip along at nearly 100 knots faster than the Phenom in worlds more comfort and capability. If speed were not an issue, I'd stretch out in a Caravan. Other than "sex appeal" I have not seen a "light jet" that impresses me, although they certainly are improving. Frankly, I'd rather have a Pilatus.
Can't go wrong with a King Air and easy to sell if you decide you want something else.
