+1

My favorite combo is to use the Rpi UART with a nano arduino that has 8 ADCs @ 
10bit and you can get them for like $5. I like to make the ardiuno dumb with a 
modbus slave. The combination with the UART/MODBUS is extremely reliable. You 
can also pump it out to tcp with the mbusd utility.

Just some thoughts

an 8 channel ADC at 10 bits resolution.
