Yep, if it were me anything that can be shipped easy would be put on ebay. The lift, you get what ever you can so YOU don't have to move it! Let me put it this way my brother sold his shop a few years ago with a couple of above ground lifts. About a year later the new owner called him and asked him if he wanted one he could come get it for free, THAT is how much they are worth.
This is the thing, as pointed out, when you can order a brand new one that you KNOW works and will work for years to come and have it delivered to your door, often financed, that is where you are going to get one.
