Cool.  They seem to report on ALL sales for a machine, not just current or recent sales.  So if a machine is trending up or down in price, that is pretty much washed clean by the older data.  For example, I looked up my machine, Theatre of Magic, and there is data going back to 03/2010 so it is hard to see what current trends are without exporting the data manually and running it through Excel.  I mean, in 2010/2011 it was selling on average for about half of what it is in 2013, but the overall average is pulled down by the old data.
