Amazon listed the best price, the vendor was quick in shipping, the product is every bit as good as I could have expected, this was a good purchase.
The only reservation I would list for Amazon is that the time delay when I make an order is 3 to 4 days before they process the order for shipping, Amazon gives some time for customer review and cancellation of an order and I can understand the problem with folks canceling orders and the item is already shipped.With Amazon's experience as a seller I believe they have it right, I'm not the patient type but this wait has been worth it.
The WK-500 is better than I expected, I like the 76 key size, I had looked at the weighted key models but after using this one I'm glad I saved the money and I like the keyboard feel of the keys on the WK-500, they aren't weighted but not cheap feeling like I thought they would be as I have seen on some keyboards.I would say it has a nice action if you can call it that and has reasonable touch sensitive control settings although the default setting appears the best.Good overall sound, when I first got it I was slow to adapt to the different control setup than my smaller 66 keyboard but quickly became at home the Casio's setup.I also thought that the dull black color would be less attractive than my preference would be the higher luster silver type I kind of expected of a keyboard but again I was wrong as the black mantle look matches quite a bit of my other stereo and computer stuff and looks fine.
I'm not an expert on sound quality and keyboard features however I am impressed with both.I have had this about a month and have not used the advanced features like computer hookup etc. so I can't comment further.
