WTB: Flute

I'm a guitar player who wants to learn to play flute, Jethro Tull style.

Anyone have a nice playing, cheapish flute they want to sell? Or can point me towards some decent deals on trademe or marketplace.

Chances are moderately high that I'll give up and resell it - I'd like to not lose too much money in the process if I do give up on it. I want to try with something that's not a piece of rubbish though.
