Russel, Last week I asked a question about what processor would be good out of the Z8, AVR, SX, and SST's "FlashFlex 51" family. I received about 4 emails straight to me. They all had used ZILOGs chips for sometime. The thing that caught my attention was that they all basically had the same complaint, ZILOG seems to have this habit of changing their die and not telling people. A few people did say that overall ZILOG is a good chip for selection, price, and are great number crunchers. Hope this helps, if you decide to go that way let me know how it works out.
