Traffic domain appraisal

I have a domain that has been getting 500+ unique visitors each month for the past 6 months am not looking to develop it atm i just have a wordpress install to track the visitors instead am looking to sell it any idea what to price it ? i hardly ever sell traffic domains so i have no idea btw it was previously developed as a download site for movies

also where to sell ? is there a marketplace for traffic domains ?

no ideas ^^?

I think sedo has a category for domains with traffic, but I'm not sure if it's sedo or someone else but I remember having seen it. Or was it flippa??

$200-250 seems like a reasonable asking price... that's what I'd be OK paying anyway if I wanted the domain
