Check out Value Electronics in Scarsdale, NY. ISF Professional calibration offered for all TVs (addl. cost). I've purchased my last two OLEDs and have always had excellent customer service.Anyone with experience buying direct from the manufacturer (LG, Sony, Samsung) vs Amazon vs Best Buy? They all participate in the UPP (Universal pricing) so the price is the same, but I don't know the differences in service. I can get a corporate discount from the manufacturers.
