Digital BW, The Print

Does anyone here have input as far as shooting digitally vs. 
scanning transparencies or negatives?  I have heard that you 
can get more latitude with digital.  Also, you don't have to worry 
about the whole scanning process and paying for good drum 
scans if you shoot digitally if the camera is capable enough.  Do 
most people in this group scan trannies or shoot digitally?  What 
level camera do you need to be able to print good 16x20's or 
bigger?  How big can you print with a 6 megapixel Canon 1D, 
D60, D30, or Fuji S2?  I'm curious to see what people are using 
to create their images.  Thanks!
