I can't find a domain that sold at a similar sale price on dnsaleprice.com, the sedo estimation put it a 349 but I don't trust that thing so if you could give me a good estimate I would appreciate it!
(p.s. if you would like to buy it then you could leave an offer as well)
Have you checked namebio.com ? The most recent transaction on musis was musictribe.com at $2288. Musicsite.com sold for $611 a few months ago. Now, keep in mind that .org domains typically sell at 1/10th of their .com equivalent. So I doubt your domain is worth more than $xx
Sorry to be negative. May be some other forum members will be more encouraging.
