Sensirion has the SCD40, which appears to be based on the same principle. It's much cheaper than the SCD30.

Yes, SCD30 series are optical while SCD40 series are photoacoustic. STC series are thermal conductivity based. STC and SCD40 are smaller than SCD30 but less accurate if memory serves (check datasheet).
