I cannot see these costs being all that high. The number of people selling 9xx must be very small compared to the number of people keeping them. As long as Dish allows people to keep 9xx, there will be extra maintenance costs. The incremental costs of a few more 9xx users is pretty small. Maybe in a couple years this is a good strategy, but not with current 622 production costs. Isn’t the lease fee waived for new customers on the first receiver? This means a 622 and 921 customer has the same monthly receiver bill. Dish would love to sell customers receivers, but competition from cable and DirecTV force Dish to offer lease. Just look at the minium requirement of AT60 to lease. If leasing really was profitable, you could lease without AT60.
