It sounds as if the TI is new to you, Stuart. It seems to me that some 
TI version is the only way to make sense of the empirical world as I 
understand it (including presentiment, etc). But Cramer's approach has 
been critiqued in, e.g., Michael Price's Many World's FAQ:


< 5) Transactional model [C]. Explicitly non-local. An imaginative 
theory, based on the Feynman-Wheeler absorber-emitter model of EM, in 
which advanced and retarded probability amplitudes combine into an 
atemporal "transaction" to form the Born probability density. It 
requires that the input and output states, as defined by an observer, 
act as emitters and absorbers respectively, but not any internal states 
(inside the "black box"), and, consequently, suffers from the familiar 
measurement problem of the Copenhagen interpretation.

If the internal states did act as emitters/absorbers then the 
wavefunction would collapse, for example, around one of the double slits 
(an internal state) in the double slit experiment, destroying the 
observed interference fringes. In transaction terminology a transaction 
would form between the first single slit and one of the double slits and 
another transaction would form between the same double slit and the 
point on the screen where the photon lands. This never observed.>
