At this time, I really do not have a BIN. Feel free to make me a reasonable offer and I will take it into consideration.
I personally find Estibot to be okay for establishing a baseline price reference; however, as you likely know, the true value is what an end-user is willing to pay for it. i have sold domains for $x,xxx which Estibot valued at $xx, and likewise I have had domains Estibot valued at $xx,xxx and I couldn't get move them for that.
Thanks for the interest. Feel free to PM me if you want to propose an offer.
