Perhaps the obvious is worth stating in this discussion --
not only is the 68000 a lower-cost part then the 68020,
but it has a 16-bit bus vs. the 68020's 32 bit bus, and
a somewhat simpler set of control signals.  Therefore, for a 
low end system, the parts count and parts cost will be 
considerably lower for a 68000 system.

Therefore, which part to use primarily depends on whether
you're aiming for a 16-bit or 32-bit system.

As I recall the 68010 is a 68000 with some hack that some
VM system designers demanded.
