Best Arduino for lots of ADC

Projects General Guidance

I'm looking for an arduino/shield combo capable of at least 10 ADC channels. The Mega has 16, but is a bit expensive, and includes a lot of other features I don't need. Is there a cheaper arduino with just as many ADC pins, or some shield that provides more ADC pins?

Look at ADC chips with an I2C interface.

Use two MPC3208, 8 ADCs each with 12 bit resolution, easy to read with SPI commands.
