I snipped it to just respond to the part that related with what I had to say.
I look at it like this: You buy a new tractor; your wife wants you to sell your old one but you don't want to. You can say: "Honey, I'm not selling the old one." and guarantee you'll be on the couch for the foreseeable future. OR, you can put it on craigslist for $10,000 more than it's worth; ensuring no one will buy it.
In that same listing you have a bunch of tools and implements you also upgraded when you got the new tractor and you have those listed at reasonable prices. Suddenly, all your other stuff is moving, but Honey, no one wants the tractor...
