I need to sell my camera! How much should I sell it for, and where

So, I have made the decision to buy a new camera, the nikon D90.but, i have to sell the one I have right now first. It's the olympus Evolt (e-520). I bought it for a little over $600 dollars. I've only had it for 8 months too. I was thinking of selling it for around $515.
i need some imput on how much i should sell it for, and where!

It doesn't matter how long you've had it. You can get an E-620 for $479 with the kit lens from B&H

So I would say that $400 may be a better price to ask. I would list it on craigslist.

Why are you selling the camera though? You should be aware that you aren't going to get any better results with a different camera than with the one you have now.

515 for an 8 month old camera which cost 600 dollars - You are joking.

As soon as you took it out of the box and used it then it was worth less than that.

You may be able to sell it privately for a bit over 400 but if you were to sell to dealer then it would be more like 250-300.
