Oklahoma Joe Longhorn.

Worth ... as in to buy or sell ... or flip?

Don't understand if it's 16" or 20" diameter. But I can tell you I just sold a 16" OK Joes (about identical to the Classic) for $375.

Something like that would run, what, 1500-1700 new?

By "FAIR" condition you talking serious rust or cosmetic?

The Chuckwagon pit I picked up is 'bout the same as this one. Has some firebox rust issues. Seller was "motivated". I got it for $100.

It's a good sized cooker, and if I was looking for one and it was decent I'd say $250-$500 would be 'bout right. My $.02

YMMV, of course
