The KX is a lot like the KX but has a much better meter display. You can see through the viewfinder the aperture, the shutter speed and the suggest shutter speed (basically it is Pentax's version of the Nikon FM). The camera uses the batteries for the meter only and can be used without batteries.
This camera shows light wear and works perfectly. The shutter and meter work well. We have replaced the light seals (a $75 value). The lens is clean and scratch-free. A lens cap and fresh batteries are included.
