The leatherette cases for the SW100s and SW07s are also hard to come by.
The most common issues for me is the battery holder where the end breaks out, and corrosion on the boards where people have left batteries in and they leaked, and of course the cut ribbon cables.
The most common issue with the SW12s is the battery contact (where button battery slides in) breaks loose from where it is soldered.
Have found no issues with the SW07s.
