You will have to do a search on Ebay and craigs list and see what they are selling for. If you can't find anything, find the closest new TV that has the same features and use it's price. Since it's used, consider 50% to 75% for that. I personally wouldn't pay more than 50% of the purchase price of a new comparable TV.
BTW, how do you like it. My father-in-law has the LN52B750 and it has terrible digital artifacts so bad, it destroys the benefits of high definition. It does look to have better black levels and off center viewing angles than other CCFL LCDs, comparable to LED LCDs or Plasma. I was impressed with that. If we could clean up the picture quality correctly, it would make a world of difference.
Also while watching content with over and under black bars, the inner top bar edge was uneven like a section of it was moving back and forth.
This was a replacement after fighting Samsung for over a year on repairing their 8000 series TV.
I'm going to calibrate it after I calibrate their new LG 47LW5600 (same as mine) for their basement home theater.
Sorry but your the first to bring up that model so I thought I'd pick your brain a bit while giving the best answer to your question that I could come up with.
