want to buy a mobile

i live in the Netherlands and i want to buy a mobile.
i say this because each country haves its different prices.
the max money i want to spend is 300 euro but i dont know wich one i want to buy.
i prefer a slide phone because i find them more beautiful.

these are the ones i think about to buy:

samsung u600

Samsung SGH-E840

wich one should i buy?
you can say other mobiles to.

The second one.

i always go with sony ericsson + the headphones you get are really good you can't hear anyone else and thats what makes the music sound so loud
