Depending on the condition, used ones have been selling pretty high, as much as 1500 dollars. I only paid $995 for mine new a few years ago, so the prices have went up.
You will get more selling it on ebay, but you also have to pay fees. If you have a good ebay reputation, and the original box and accessories, $1400-$1450 is common. You should always be able to get $1100-$1200.
If you can sell it for $1250 locally, you will come out ahead.
