This has got to be the cheapest piece of insurance around. Normally, I do not pick up the warranty option. However, with my K20 Pentax offered as part of the package. 18 months later, I was getting terrible noise so I sent the body in for warranty repair. Pentax replaced the sensor and the main circuit board - essentially the guts of the entire camera. For the $9.99 or $19.99 or whatever they are charging for the K5 warranty (at least in this price range), its has to be an absolute bargain of the year. On the K20, it includes a free cleaning - so that alone is worth the price.
