I'm in the market for a new digital SLR and happened upon this fascinating site for something decidely low-tech: a large-format pinhole camera called the "Snapdragon."
Since it is, as you can see, totally manual, they recommend the "Point and Pray" method to control the exposure.

What kind of film does it use?
As to digital, glass is very important, stay away from CMOS, and make sure you can do everything manual if choose to do so. Else you will wish you did.
I see they recommend the "For Thine is the kingdom" bit at the end. As with so many things in our culture, a Catholic photograph from a Snapdragon would be relatively underexposed.
Are you looking for a pro-am or a full professional unit?
I am looking at the Canon 20D.
