I've now asked via chat and via phone call about buying an H3. After much referring to their supervisors etc., it seems that there is no price for me to buy my existing leased H3. (just as crodrules stated) I had to hear it for myself from them, and register my miniscule opinion that it should be possible for me to do that. I think they said that "their system" couldn't handle changing the coding of a receiver from leased to owned. That pesky software again.
They've quoted $350 for an H3, and stated that it would be "new". Thinking about it, considering the 35 month break-even vs. continuing to lease. I don't really like leases.
I don't know how much to trust a refurb that might have high mileage on it to save 100 bucks.
Of course, if the H4 came out with its 256 tuners, customer-installable apps, guide data 3 months in advance, and on-demand movies that aren't even released yet, I might feel like I was missing out.
