I personally would only pay 35 TBT MAXIMUM, less if I could negotiate my way through. But in my opinion, anything more is noth worth paying, unless you're THAT attatched to him. Also, keep in mind that 1 TBT = 200k IGB, you do the math.
Well, people say different things for how much they like him, but yeah, 25-35 tbt is the going rate.
(not to wreck the btb economy or anything but I think 200k = 1 btb is a bit inflated.)
