Anyone got any idea what is the best flute i can get for £1000/$1600??

There are many, many threads on this subject. Please read them, we're all sick of repeating ourselves.

Hi,

Try to do a search on the forum. There are indeed many threads about it.
It you remain in doubt, though, please return here with your question(s).

I'd recommend you to take a look at www.fluteworld.com (USA) and www.justflutes.com (Britain).
