Hi All, I went to the local music store (in Guayaquil) and found my two keyboard options for the price range I have saved... the CTK-900 vs. the CTK-5000. Does anybody have something to say about them? From what I have gather on the internet, the 5000 has an arpegiator, on the other hand the 900 has effects and a lot of drawbar organ sounds. Also the 900 has the ability of being able to download new songs from the internet, but again, no arpegiator. Can anybody give me any light as of which one is cooler???
