I second the Vistaliners vote of confidence, Erick Cantu's 722 is a work of art - although I haven't seen a Northwest repaint for it. However, over at SimV's sister site HJG, they have Erick's 727-100 with a Northwest livery (also a brilliant model), and as a bonus there's the Richard Probst panel, which combined with the 727 is almost as good as it gets for a non-VC plane.
There was an update to the Probst panel posted here a few days back which adds full fuel panel functionality . I have downloaded it but haven't tried it yet.
