That's a tough question to answer since there is really no price guide for trad bows. Many of us check the completed listings on the big auction site, but there are so few of the early Bear TD's that are sold and bought.
With that said, I regard that bow as one of the most desirable, and therefore, one I would love to have. Prices for these are all over the place, but seem to be going up in value over the past few years while other trad bows (even the common Bear ones) are going down.
So, the old saying of "a bow is only worth what one is willing to pay" is pretty much the case with this one.
I know what my max would be in buying one, but I will not reveal it here.
