Darn. That means spending another $50.
If you want 2 Hopper 3's you'll have to spend a lot more than that. You'll also have to buy the second Hopper 3.
If you contact DISH and very nicely tell them of your problem you could probably talk them into a free or almost free upgrade to 2 Hopper 2's which would be a marked improvement over the 2 Hopper 1's. That shouldn't require any equipment or wiring changes other than swapping out the receivers.
