I have a Nikon Nikkor AF-S DX 18-135mm f/3.5-5.6G IF-ED. Nikon.ca is selling it for $330. I used it for about a month before upgrading and haven't used it since. I'm not trying to sell it on here, but I would like to know what I should be asking for it. I want to be fair but i also don't want to sell it for so cheap that whoever buys it can turn around and sell it for more. I haven't sold anything like this so I have no idea what I should be asking for it! Thanks for any input!!
