Mine was built in 1999 and was just over $700...a new one now is twice that amount.
if limb was not twisted I would think it would be worth at least $600 all other things being good. With the twisted limb maybe $200 as if you have to have Chris Cox build a set of new limbs they will run a couple hundred each I imagine.
I would call Chris Cox and find out when it was built and check with him on straightening the limb and get more info....
I am just speculating above...
Here is mine....
