Ill say 25$ because it as 9T3 (93) so good name try to find good seller if you dont want to develop site on it.
I would try posting it on some of the "Entrepreneur" web sites: startupnation.com, youngentrepreneurs.com (I think) and others. I contribute to some of these and they are a different bunch than found here at DP (no offense). They are always brainstorming for slick names for different startup's. I personally think 9t3.net is sleek and very easily brandable. Great company name & domain to match. Also, I came across a post, here, from a guy looking for a short domain that doesn't have to mean anything...but was talking about offering good $$ for one....$2k. Your domain is worth much, much, much more than the feedback you are receiving here, in my opinion. I believe there are many factors that aren't taken into consideration when people often give a quick response as to the value of many domains. Most of the time the general opinions of many are close but this time I think they are way off. Also, many people are cruisin' & scoping out domains to purchase...I don't think all are purposely undervaluing domains but we have to remember that it is natural to be biased, whether you know it or not, when you have a direct or indirect financial interest, especially when openly asked for an opinion, in items of potential self gain. I'm not slamming those that posted here regarding 9t3.net's value. Any product is worth what another is willing to pay for it....and I think those most willing to pay more would be entrepreneurs that are not exposed to the sale of so many domains on a daily basis and are looking to build & launch a new entity. But what do I know? I will post the thread URL here, I mentioned above, in a minute.
Here it is.... http://forums.digitalpoint.com/showthread.php?t=1025076 I will also post this over there. Good luck!
