Fortunately, I've never had to sell any of my console game collection but I did sell off quite a bit of my Commodore Vic-20 collection. At that time I was very short on funds and overtime was practically nonexistent. Luckily, I was able to talk the buyer into selling it back to me after I squared away my finances for an extremely generous price and got a good friendship out of the deal as well. If I hadn't been able to buy my Vic collection back that would have been very regrettable to say the least.
