I just had two Hopper 3's installed by DISH. The approved of having two and in fact suggested it (I have 8TV's). They worked great until a few days ago when evidently due to a software release they had some problems that they are working on. But yes, they now approve of having two Hopper 3's on one account. I had to buy the second one, but it was much cheaper to buy them myself rather than from them.
