I am interested in the Toshiba 46HX83, but cannot find a dealer in the Northern Virginia area. Does anyone know of a dealer that carries this set? I know some of the large chain stores carry the 46H83, i.e. Best Buy and Sears, but I am interested in taking a look at the HX model. Is the HX worth the extra money over the H model? Any help/suggestions would be greatly appreciated! Thanks.
