We all know that the list price for Business.tv is a joke. It's worth closer to $50,000 but even that seems a little high to me.
Interestingly, I've been reading some of the comments from the so-called expert appraisers here on Namepros and many of them use Estibot as a basis and then adjust from there.
Let's look at the Estibot basis:
Business.tv = $46,000
Newyorkbusiness.tv = Reg Fee
Using this basis, I (as a rookie appraiser) would tend to think that $46,000 is about right to a little high and Reg fee for the second domain is on the low side, but not by much.
