Anyone ever used one of these before??

I'm bidding on one on ebay - and was wondering if it's any good.

Obviously i'm not planning on using it for full on Vai-esque whammy bar madness - but what's it like for more subtle uses?
um, pardon my ignorance, but what's a bowen handle?

Ibanez SoundGear SR300DX Bass

Digitech BP200
A bowen handle is a trem arm system for T-O-M guitars - it replaces the stoptail with the vibrato usit, so it is totally reversible and easy to install - no drilling!!


there's an american compnay selling them, but i'm from the UK and can't be bothered with paying international shipping!

any thoughts/comments/reviews helpful
i have one, but it makes your strings go out of tune every time you do the slightest vibrato
