again, thank you all for your greetings.

Scott: the word "bomba" came from "bombastic".. I think it's an English word, right?

Rice: I did a mistake... the first kb I checked was the 3k.. now every other kb will not sould imprasive as the 3k.. I should have check the 2k, 2100, 1500 before the 3k...
The arranger community in Israel is not so developed, and this is impossible to find a used 3k.. Plus, I will not get that high price for my 630 without the trade-in offered me in the store.
Because we are in the middle east, people are selling mostly oriental kbs from Roland, Korg...

I saw an add for Tyros+stand+speakers for 2200$, but this sound suspicious, because new one costs at least 4500$ here...
