Someone mentioned Lightobjective in California as a source for laser components, so I was checking out their offerings. I noticed that in addition to the CW5200 chiller (1400W) they also have their own offering, the Lightobjective 1650. Has anyone tried one of these? Any preference for the CW5200 or Lightobjective 1650? Price is comparable on the two chillers - $665 for the CW5200 and $625 for the Lightobjective 1650.
