I'm not sure. When I bought my Dark Lord, I paid $250 for it, but at that time, they were very few and far between. Now, there seem to be more popping up for sale, culminating with that stupidly priced one.
I tried to sell mine for $200, but mostly in hopes that I could turn it around quickly, even if I was taking a loss. Unfortunately, it never sold... Seems like I'm getting some interest now though. We'll see.
So in my opinion, $250 is probably closer to actual value, though $200 is right around there.
