Seems like every "mean dealer" thread (in any field, just not audio) has a smelly customer in bib overalls buying $200,000 story.
Most dealers today, at least the ones I have encountered, are super friendly. Most do some sort of Home Theatre business as well. Selling $600 Yamaha A/V receivers, soundbars,...you name it. I'm sure there are exceptions.....my experience has been the opposite. The only issues I see is lack of display model on something newer, except McIntosh. Mac dealers generally have the newer stuff pretty quick.
