I have read that the Katz Eye requires some type of modification in order to be accurate (shimming, I believe). I probably would not care to do this, as it would would open another "can of worms" in regard to equipment (my used equipment has been a source of some problems over the years). Your points about being revitalized about photography are very significant. I am at a point where processing and equipment issues (used equipment sometimes fails) have made me want to give up photography.
Don't give up on photography. I think you might be happier with the K-01 or a Sony NEX. Focus peaking is amazing and, in my opinion, better than even a film viewfinder for accuracy. You'll never be happy with the tiny viewfinder in the K-5 since you're a film guy. Either of those cameras will work with your Pentax lenses. Some say that the K-01's focus peaking implementation is even better than the NEX. With focus peaking I can nail low DOF shots, and both of these cameras have the same sensor as the K-5. The K30 will also have focus peaking so you can choose to use it or the viewfinder. It also has the dials you'd be looking for, and the K30 has hot swap-able focus screens, so you don't have to calibrate them.
