Was going to part with my antique D6000 with both modules and take the $25 buy back when I skimmed over to e-bay and saw that they were going for insanely high prices. I can't figure this out. Even though I paid close to a grand for this first generation HD receiver, it just doesn't seem to be worth the $150-250 bids they are getting. I'm not greedy, but would rather just deactivate it and keep it for an antique. Any insight as to why the 6000 seems to be more valuable than an 811?
