Although I'm hesitant to get into this debate, it makes a lot of sense
for someone with PIC experience to design some veeery simple PIC code to
to use a low cost and easily reprogrammable PIC like the 16F84 (US$3.90
from http://www.futurlec.com/ICMicrochip.html ), and an external A/D
converter, and forget the LM3914, which IS overpriced. It would be a snap
to add RS232 as well.
