im not 100% sure of this.
but i "believe" the Module needed to view dish HD channels can't be added within the box and sold as a regular 100% legal to buy-own FTA receiver.
as it would only serve one purpose = decrypting echostar birds.
thats why no HD unit i don't think will come with this,you will have to add something like that after,
this way the co's are NOT responsible for what you do with it once you buy it.
again,this is all my "best guess"
anyone feel free to correct me,thank you.
