First post, so be gentle.
Another YMMV - Walmart thread. Was in store for the Vizio E60-E3. Was about to purchase when I saw the new clearance price on the 55" Q7F. Been monitoring it, it had been 1299$ at my store for the longest while, and just now 799$. Not sure how good of a deal this is, but definitely got the interest of the Walmart sales guy. Probably bought the last one right after I left.
Just a quick heads up, when researching this tv and its possible issues, you find people with issues with the TV suddenly turning on and off after a couple of months, due to the connect box and faulty cable that comes with it. Maybe getting an extended warranty would be a good idea.
