If you just won it at aution that is probably a better indicator of its current value than anything I can say.
I will say I like it and think it is brandable but I still have to give it only a 7 on my 4 char scale. I am not as versed on the premium letters and such or current values but I think it is a lot more useful than a lot of the stuff I see here.
But I just bumped the thread so we'll see if anyone else has anything to add.
