Drudown, you are incorrect.
To ***LOG*** PIC time in the King Air B200, as the "sole manipulator of the controls", you do NOT need a high altitude endorsement. Of course, there better be someone else in the other seat who is qualified, and is, ACTING as PIC, because you cannot ACT as PIC in the BE20 unless you have the high altitude endorsement. There are numerous areas on this board and others (like "Doc's FAR forum" on www.propilot.com and John Lynch's pages which are somehwere on the FAA's website) that go into the differences between "logging PIC vs. acting as PIC" ad infinitum, which are pretty interesting and explain this concept in detail.
