I disagree there. If i wanted to sell my SDN-6 (for example), AND i was willing to sell it for $400...i bet i could find a buyer. $1200 for a new one or $400 for a used one is a steal.
The problem is when a new can (22lr) is so cheap. I couldn't reduce the price on my used one enough to make it worthwhile to buy it used
Just like all things PRICE/value makes or breaks the sale. Selling to an out of state person makes it a bigger deal.
