There was a 7720 Titan II 1985 with 3100 hrs on it that sold at an auction around here for 21,000 on the 9th. It had new cylinder bars, concave, sieves, straw chopper, walkers, rebuilt unloading auger, two owner machine and the two owners lived 15 miles apart. The second owner bought it 11 years ago for 25,000. Not too bad I'd say.
