Reseller value for me would be less than a few hundred, but I can be corrected. publishing ads on the doman as a site might not cover your renewal costs. End-user though might have value, all i can think of at the moment is a slow-pitch league wanting it, and if thats the case i dont see them paying alot for a domain.
Tough one to appraise, sorry im being so vague. Hopefully someone else can leave some input and help you out more. I do know alot of the resellers would put a price of low to mid x,xxx. on it, but I feel its below x,xxx undeveloped.
