I am sorry to say it but in the world of flutes a decent keyless one may set you back as much as 6-700 euro or more. The two flutes in your picture are considered very cheap ones and you may want to read the thread on Pakistani/cheap Ebay flutes on the flute forum.I also included two rather expensive wooden ones which are considered of being of high quality and I like wood anyway. That way i can't blame my fails on the instrument, ha ha ha. Since I own pretty high quality guitars, a flute for around 175 to 199 Euros is still acceptable for me and I dared to order both.
Anyhow, welcome and good luck.
