Hi,
[...] i found some that only costs $10 here in denmark,
You won't get anything even moderately cheap in DK!
If you can wait for delivery (like a couple of weeks), DealExtreme.com is THE place to get a low price.
Where in DK are you? There are high street vendors in most major cities.
(If you need help in Danish, just drop me an email, I'm a Dane myself).
