I was dragged into it myself by a part that's not 5V tolerant.  Not too 
bad.  You give up ICSP, though.  (I mean, I'm sure there's some 
brilliant way around it, but I just grab the ZIF socket.)

16F916 is my 'usual' now, or 917 for more pins - though there's now one 
that's cheaper and has PWM instead of the LCD interface (which I've 
never used), don't know the number off hand.
