Some info on aperture and shutter priority cameras:

	o  Aperture priority allows easier camera setup for depth-of-field.
	   
	o  Shutter priority allows easier camera setup for fast action shots.

This does not mean that you can't setup a shutter priority camera for depth-
of-field, or an aperture priority for fast action.  It is just not as 
convenient.

I tend to think in terms of shutter speed, so I bought a Canon AE-1 Program
camera.  I love it!  I use the manual mode almost always for my serious work
and save the Program mode for lazy days.  The camera is shutter priority, but
allows you to stop down the aperture before shooting to actually "see" the
depth-of-field.

A word of warning:  The Program mode on any programmable camera DOES NOT
	            assure you of perfect pictures.  It works quite well
	  	    under "average" conditions.  You will, through experience,
		    understand the limitations of the program mode and how to
		    deal with those limitations.  It's a challenge in itself!
