As the guy said, it's a midi drummer device (there are like hundreds of pictures of these and DJ mixers [not sure is it the right word] on this forum)... He also put a link, you can see it in the quote in my previous post...
Me too...
Well, what could be expensive on a keyboard? (by keyboard, I mean a normal keyboard like on the pic above, not some crazy spaceship keyboard with screens and shit...)
That's in Zagreb, our capital... And I live 125km away from it in a "town" (it's more like a pile of shit), so you need to add the transport prices, and like 10% profit for the store my bro bought it in... Also, it was like a year ago when he bought it so the price went down a bit.
