Starkeeper, Nope haven't had the chance to try the new Casio's yet. It's nice that it has 76 keys, but I'm lookng for something that's weighted. Yes 6 tracks wouldn't be enough for me. I have to have 16 tracks. I feel so limited when recording songs on keyboards that only record 6 tracks and have no loop options in either the standard recorder or style recorder. Plus the WK doesn't have a style recorder like the 550. Let me know what you think of it too. I used to own the MZ-2000 so I pretty much have a good idea what the WK's sound like..
