  I don't know about cheaper.  The last time I was princing C30 chips 
they were running $270.  in quantity.  However, the C31-27 could be 
significantly cheaper.  Call your local reps about that.  

   My preference is towards the C3x as well.  Much of my DSP expertise
was cut with this device.  IN addition I like the feature of the dual
busses in the same memory address space.  This saves a lot of hassles
in coding and design.    
    I'm not sure, but I do not think that the 56K supports the following 
features that the C30 does:

	a)  parallel instructions
        b)  serial ports (2 for the C30, 1 for the C31)

  Graphics, particularly maldebrot fractals.
