Hi, I currently have two HR10-250s and really enjoy them. I am adding a new plasma TV to my gameroom and would love to add a third unit. I believe that DirecTv has moved on to a new HD DVR that isn't Tivo, but I would much rather have the Tivo HR10-250. Does anybody know where the best place to get an HR10-250 is? Does DirecTv still sell the HR10-250 units? Any help would be greatly appreciated. Thanks.
