And the seller may be assuming the same thing .. In many (heck, maybe most) cases both you and the eBay seller are wrong
That was an assumption on my part that the HRs for sale on eBay are "owned". Some people have posted that they have "owned" HRs. There is such a post on this thread. If that is the case, you certainly may sell the "owned" HR on eBay.
If these people are selling "leased" units, they are obviously opening up the possibility of getting charged by D* for the cost of the unit. Somewhere around $500, I think. Why would someone do this? Beats me. But, if someone is dumb enough to take a chance like that, I pity the poor fool. I was surprised to see that many HRs for sale. But, they have been sold on eBay since they were first set loose on the public. All you can get for them now is about $200.
Where am I wrong?
