I'll go with the Dr. and TLAW.
Charge yourself at least $100 an hour and do 100 hours a year (to at least get value from the Annual) if you own your own simple cross country machine with an anticipated long reliable engine life ahead. Do 200 hours if you have more of a need, on private operations. More $/hr for the more sophisticated types. Or at least $200 an hour (or more), if you hire and do 50 hours a year on your private ops. A good mix for a Commercial Pilot would be 800-850 for the Company, and 50-100 hours for yourself to stay sane..! (More would depend on your commercial maximums).
