i almost did the Dish/Sharp deal a few months back. but at the time they were out of stock, along with most other retailers. just so happened that QVC had a "today's special" on the 46" inch i wanted and that is what i did. my wife could stomach the "five easy payments" better than the lump sum check crutchfiled.com, that was another site that had it for about the same price i believe.
Like others are saying, better prices for the same model Sharps can be found and had. I did quite a bit of price research on this. It is quite sad that Dish and Sharp could not come up with better prices. Quite frankly, it costs more money going through Dish for the Sharp.
