I wouldn't do it. After the initial coolness of the newer design has passed, you'll probably in the long run enjoy either set about the same. You'll get used to the "improved picture quality" and i'tll all be the same. 1 year into owning the TV, it'll just be a really neat TV with a good picture and you probably won't be thinking much of the other design you passed up, and you'll have saved $500. I'm a bit sedated right now so that might have rambled oddly.
