Does Dish stand behind these or do you have to deal direct with Sharp?  
 
A few years ago Dish had an association with RCA for HDTVs but I heard that when people had problems, they had to deal direct with RCA.  To be fair, I bought one and it's (KOW) still going strong, so I can't attest to how well Dish stood behind them but I do remember reading a few horror stories here.
