if your not too worried about the price per chip then i belive the dspic30f
series are essentially the same as pic24s but with a few extra instructions
and running on 5V.

unfortunately none of the dspic30 series seem to have the analog input count
you wan't, it looks like you'll have to go with the 3.3V part and if
nessacery add level shifting (note though that level shifting may not
actually be needed, check the thresholds of the inputs on the 5V devices and
if the inputs you plan to use on the pic are 5V tolerant).
