Moving to new location that does not allow satellites, HughesNet is telling us to pay a $600 for equipment.

First time I ever heard of the lease fee being added into the ETF. They may not charge you anything as long as you return the modem and radio from the dish. Especially since you are moving to a place that doesn't allow it. Have seen them ask for some kind of proof though, not saying they will but maybe. Good luck!
