I own this domain and manage an art site with it. Unfortunately I couldn't pay hosting this month so it's down right now but it's a vBulletin forum with a unique design. Is the ( unique ) 'brand' worth anything? ( arteea ).
I quite like this name. As you stated if it's developed page and receives daily visitors I think it should be worth around low $xxx - mid $xxx ( need to know that also license for vBulletin is worth something ). Also page rank 2 and some Alexa traffic. Good luck with it.
