Hey Russell,

I have had many good experiences with the 819. It's my PIC of choice whenever I
need an 18 pin micro. I also use the 819 for training coworkers. The 819 is
straight forward with no unexpected behavior, and half the price of an 84. In my
opinion, it's a great chip.

BTW, I have not tested the 819 above 8 MHz.

Later,
Steve
