None, because its hard to get the needed parts around. The 68k is discontinued at Freescale.
Are you sure about that? I was under the impression that Freescale was still producing 3.3V 68000 - 68060 chips. The best thing to do is to go to their website and check the official status. IIRC, the old 5V DIL chips are discontinued; surface mount versions are still available.
