I would like to check out the 60XBR800 and the HLN/M617, but I can't find any stores who have them. Typically the 50 inch models are the ones they have on display. I really want to see these sets before making a buying decision. Anyone know of any dealers in the eastern PA area that carries them? For anyone who has seen them, is the PQ on the 50" versions comparable on the 60" versions? Thanks for any replies.
