Please give price ranges for the following tractors.  I know these were made in different years, so just put a price range.

JD 8300 Tractor w/6k hrs.

JD 8400 Tractor w/6k hrs.

JD 8410 Tractor w/4k hrs.

 Assume all tractors above do have mfwd, quick hitch, 3-4 scv's, good rubber, reasonably clean

I would like price ranges, for example JD 8300's w/6k hrs: 54-62k, and then give a center $(what most of em sell for)

It seems to me that tractors vary in price, widely, according to where (in the US) it is located/being sold.  Since I am in the panhandle of Texas, I see that tractors in the corn belt are generally higher priced than they are in this part of the world...Good, bad, or otherwise--that is the way it seems to me....

*I would still love to find a tractor blue book website, where a person did not have to pay for the info.*
