In the latest builds, I've been substituting an AD8691 for the chopper amp. It's a low noise amplifier rather than a low offset amplifier, and offset errors don't really matter so much since they're corrected by the discipline. Low noise is more important for this application. They're also a little cheaper than the chopper amps.
