I have a Pioneer KRP-500M for sale - prefer local pick up, and I am located in Northern California- I live in the foothills outside of Sacramento and work in the bay area so a little flexible on a reasonable location along that route.
I don't know how many hours, but not a heavy viewer- the display was purchased in April 2009 and was calibrated by David Abrams in March 2010. The display also has the ISF patch from Turbe installed. Originally broken in with the D-nice slides, no CNBC or CNN viewing with logos- just live sporting events and blu ray movies.
The unit is in very good condition, always well cared for- recently moved and upgrading to a larger display.
Great display -
