I've seen loads of quality HMI's sell for severely cut prices on Craigslist LA. I drive from San Diego for the market sometimes. Some of the best deals I've seen included a 1.2k HMI with ballast for $800, a 2.5k with ballast for $600. The bigger units tend to sell for cheaper while the 15a-capable ones have more demand, you won't find Arri's that cheap though, but stuff like Strand or Desisti/Ianiro are commonly found for thousands less than buying elsewhere.
