It scares me to think that there may be aircraft out there with over
2000 TBO which are being sold as less than 1000 TBO.


TBO is based on tach time, not Hobbs time.

Nope, it's based on time in service. You can use any reliable
means of determining the service time as far as the FAA is concerned.
(Not that TBO means anything to most of us).
