I think it is realy personal if you want to spend money on new styles. If i had a Yamaha and I really liked a style I would buy it. As beakybird said it is a hobby and hobbies cost money. About Korg styles. Every month you can get 4 Free styles from the German site. Also the Italian site give you so now and then free styles so it isn't true it took years to get new styles. Also there are some places where you can buy styles for the Korg PA's. So there is no short on Korg styles.
