As you can see in my sig, I have a 2 Hopper setup.
My viewing choices differ dramatically from my adult son's and I record a lot. We could have worked around it with a Hopper and a Joey, but it would be a bit of a chore to manage because of all the potential contentions. With my setup, there is never an issue with that. I think it is a worthwhile way to go.
But, trying to do a 2 Hopper only upgrade/new directly from Dish is frustrating as they don't like to sell that model. Go with a local retail installer and it is just another day for them.
