My review is very simple. I bought the wk3000 because instead of spending 100 more for just some more feature that i don't neeed and also i can just save my data to a smartmedia card and no need for floppe disk. The wk3000 was very nice. IT's sounds fine. the sax are the best of the keyboard, and don't forget they have a organ mode that you can create/present lots of organ sounds. The piano are ok. This board is load with so much sound almost 600 of them. The cool thing about the sound of this keyboard is that when up hit the key really hard you get a sounds that's different when you play it normal, which is more real to the intruments. I still don't think that ZPI sounds a lot more better than Yamaha AWM sounds but it still good and you get about 300 of those. The drums on this board are excellent. OVerall the reason why i bought this board because it has so many more feature thatn YAmaha at this price range. This board sound genterator(ZPI) is one of casio's best sound, it is by far sounds so much better than the wk1800/1630. Also, what i like about this board is that the speaker are great. like 6W per side. soooooooo much better than yamahas'. ONe of this keyboard cool feature is that you can hook it up to your computer and go to casio music's website and download new tone and pattern to the keyboard to enjoy. I really enjoyg is keyboard i made like 10 sound and 3 organs sounds already. THis board is load with feature and things, And it's only 300!! I hope that you'll sonsider this keyboard if you're looking for a $300 or less keyboard.
