My experience is with live recording using microphones. I'd be wary of a device intended to pick up vibrations from the structure of the piano, as higher string overtones won't be moving the structure.
However, Barcus Berry has had quite a good reputation for YEARS in this regard; I'd definitely check out different models of their product.
The Barcus Berry is a piezoelectric pickup just the same as the Fishman.
I've used a Fishman transducer on my double bass bridge for years. There is no problem with "higher string overtones". You just need to use the Fishman preamp or something else to buffer the very high output impedance of the piezo element.
End user isn't recording the piano, they're playing it through the house. Yes, it would sound better with a couple PZM mics, one over the trademark and one over the bass strings provided it's a grand piano, but the Fishman attached the soundboard works just fine and it won't take repositioning of mics if the lid is opened or closed.
