If you are looking for a hasselblad set up i would probably go with the 500cm, WLF (waist level finder), or a prism finder, a12 back, and a 80cf lens.
For the finder. I prefer using the WLF as that is they way that i like to work. If you like looking into a view finder, i would go with the NC2. It is a very basic 45 degree finder.
The 80 lens is the normal lens on a 6x6 camera. So if you like shooting a 50 on 35mm format, the 80 is for you. If you like shooting longer or wider then normal you still have a lot of choices in lens. Like the 50 for a wide and a 150 for a longer.
