I've been in the marketplace for a nice modern insert for a while now and came across a used Regency CI2600. I've already gone through the 30+ pages to understand the idiosyncrasies of this insert but was wondering what a reasonable price would be? I know they have been in production since 2014 since he doesn't know the exact age but says it's like new with only a few fires in it. The pictures show a slight discoloration in the bricks but seem to collaborate what he said. He's asking $2k but would like the opinion of experts here. I feel like that may be a little high but not sure.
