Much will depend on the age of the camera and how it's been treated; I'm not sure when they stopped production, but the earliest will be around 20 years old and may therefore be nearing the end of their useful life. I bought mine in 1988, and it's still going strong, despite having been dropped a couple of times; it certainly isn't fragile, and there's plenty of metal in the body.
Assuming it is in working order, the camera is ideal for a beginner. The centre weighted metering is pretty reliable and you will soon learn when to compensate (I think the manual includes a diagram of the metered area - it's weighted to the bottom of centre).
Note that there are a number of different models - KR10x, KR10 super (IIRC). Mine, a KR10x, has additional features over the original KR10, of which exposure lock is by far the most useful.
I don't use it often, but every now and then I take it out with the 50mm lens as a lightweight alternative to my F80 + zoom. It also looks nicely weathered now...
