Unfortunately, I can't actually recommend either of these, since they're both so far out of my price range...

My problem exactly. My Seiko is a bit like the CA30 and is all I really need, since I simply use it position my flute headjoint for A. Once that is set, everything else is down to the internal intonation of the instrument, though I usually check it anyway.

Fidjit, your suggestion is no use to we non guitarists :-)
