  We extend earlier treatments of holographic superconductors by studying cases
where operators of different dimension condense in both 2+1 and 3+1
superconductors. We also compute a correlation length. We find surprising
regularities in quantities such as $\omega_g/T_c$ where $\omega_g$ is the gap
in the frequency dependent conductivity. In special cases, new bound states
arise corresponding to vector normal modes of the dual near-extremal black
holes.
