I think you could expect to find it for $600 to $1000.
The 42 inch deck also available, is more common.
Assuming that the engine sounds good and the drive seems solid, I would check the front suspension/steering and rear axle bushings for excessive wear... Lift the front and check the bushings without a load, do the same at the rear. You might also check the deck spindle bearings...
Price seems about average... check it close... this is the time of year to find good prices on tractor type mowers.
