Yeah, I've never really understood the point owning a Dish receiver. You pay extra cash to own it, save nothing on your monthly bill, and can't use it for anything other than Dish service. If it saved you a monthly leased equipment fee, or you could use it to pick up free channels or some other company's channels in the event you cancelled your Dish service, I would see the value in it.
As things stand, though, all it really saves you is the $15 fee for shipping your leased receiver back to Dish in the event of a cancellation (It doesn't do anything extra that the leased ones don't, and is basically just a nice looking paperweight if you cancel service)- so unless the equipment costs $15 or less, you lose money on it. And I think it costs a lot more than $15. I'm not sure how much exactly, but probably at least $100, right? Maybe several hundred.
It's different with like a Roku box (Which I don't have, but I've read about), where, yeah, you get it for Netflix streaming, but if you cancel, there are some free things it can still pick up. But a Dish box is just for Dish and you've got to be a paid subscriber. So if it's free to lease, you as might as well lease instead of buy IMO. Maybe there is something I am missing here, though...
