You might consider their fairly new lease option on the 811.
I think it is part of their DISHIN IT UP program (or something like that.)
$0 upfront, $5 lease/month. But I'm pretty sure that this $5/month lease replaces the $5 extra outlet fee (assuming it was an extra receiver), so you would pay the same anyway if you owned it.
I think you pay maybe $25 for shipping, but I think that is waived if you are on credit card autopay.
Also, I can't remember if this requires a trade in receiver or not.
Anyway, here is a link:
