I can assure you, something is defective, most likely the body, possibly some of your lenses. I had to do a global adjust on the K-x, and I returned several new lenses for misfocus (FA 35, DA 15, DA 18-135, DA*300), but as a result, all of my lenses focus perfectly on all three of my bodies.

Dual wheels are a major feature for me. OTOH, I have not had any focus issue with the K-x. I use the K-20D and K-x interchangeably to test AF on my lenses. They're both accurate. The K-5 I owned for a short time showed severe FF in tungsten light. No such issue with the others. I have an O-ME53 magnifier on the K-x, which helped greatly with MF.
Have you checked AF accuracy carefully? Maybe you need a global adjustment.
High ISO performance is highly exaggerated. The K-x has 2/3 of a stop better SNR than the K20D, the K-01 is about 1/3 stop better than the K-x. The K20D is easily my favourite of these for its controls (dual wheels, User and TAv modes, X-synch, buttons instead of menus) and features (battery grip, WR, pentaprism OVF). I also love the colour balance of the K20D, as opposed to the overly cool K-x and K-01.
