We report preliminary results from a survey to construct a complete, near-IR selected sample of quasars. The scientific goals are to i) compare the completeness of optical color outlier and K excess samples; ii) detect a complete sample of quasars in the ``redshift desert" 2.5 < z < 3.2; iii) determine the population fraction of red quasars; iv) ultimately measure the K-band luminosity function to z=4.

An initial spectroscopic run with WIYN/Hydra last March was designed to test our color selection efficiency and give a preview of object types and redshift range. An RIK-selected sample of color outliers was observed spectroscopically with WIYN Hydra to > 1 mag deeper than the SDSS NGP sample. Two out of 28 objects classifiable as broad-line AGN were consistent with intrinsic reddening E(B-V) \geq 0.4 mag. The reddest, faintest candidates have not yet been confirmed, creating interesting discovery space for greater reddening and higher z.
