Paul,
This statement is mostly true, but there are a couple of exceptions:
If you want to use GPS for enroute or approach navigation, your GPS equipment must be appropriately TSO'ed. If you have non-TSO'ed GPS, you can use it for "situational awareness," but not for IFR navigation.
Nav and anti-collision lights must meet TSO standards. Because the equipment does not need to be TSO'ed, you the builder are responsible to make sure that your lights meet this requirement. So far, I have never heard of an inspector requiring a builder to demonstrate compliance with the TSO standards, but it is there in the rules.
