easily answered.....
It's a dot biz. That automatically knocks the price down because it isn't taken seriously as a business web extension. Secondly the combination of letters and numbers is never a great choice for domain names unless it is something like I69.whatever.
It just doesn't look that good in my opinion. I should know, I have some and they are ugly and don't sell.
You have for sure seen some nasty ones sell at auction. People will buy whatever suits their fancy. In general though, the combination of number/letter/dotbiz, is just not that good for resale. I personally would never trust a dot biz if I was buying something like an HDTV. I just wouldn't trust them.
Another example: I own moved.biz. Sounds like a great name for a moving company right? Want to know how many offers I have had? Zero. Nada. A great name that in .com, .net, even say a .info would sell for a great price. Instead, it's a biz, and I will probably not unload it for what it should be worth. In the .com it would probably go for upper $xx,xxx. I will be lucky if I see $xxx anything.
So, do you want moved.biz?
