Well the brightness flickering problem on my RU50PZ61 (LG 50" plasma) has been getting on my nerves lately so I e-mailed LG and they said that it was probably a defect. So I will soon be attempting to get a replacement from circuiy city, at great hassle. Since this model was on clearance when I bought it in Februrary, I doubt they have any replacements in stock. This being the case, what would be a good replacement plasma to get? I want one that is 50", around the same price range of ~$4k or less, preferrably have cable card and HDMI, and should include or have cheaply available a regular floor stand. So, what are some of the best models out now that fit this criteria?
