It really depends on what type of receiver your trying to sell and then the question is it worth selling?
I got more "DISH" Equipment at my store than anyone else here, and there are many times where I would rather just sit on something than list it on ebay and give someone a bargain.
Now I do not support piracy, but piracy is what drives the cost of most of the receivers on ebay.
The problem is all this free to air crap they got out there, that is just ruining the market place for anyone trying to sell.
The only thing that I find that is really holding value is 501/508 and 721 receivers since they are grandfathered from the fees, everything else for the exception of the Model 6000 is selling for next to nothing!
