Oh, that's easy!  The Acorn RISC Machine (ARM).  Yes, I know it has a
32-bit bus now, but just talk to VTI (they have the ARM and use it as a
cell, I think):  if you are right about volumes, they'll make a mod to
give it a 16-bit bus.  On every other account, the ARM is what you want.
I think you could even get it for around $10 instead of $15 (I think that
price is currently available for large quantities).

On second thought, with a 16-bit bus, it might slow down a lot.  It seems
worth looking into though.
