I am going to buy an arranger keyboard, and I am between PSR740, KN1600 or KN5000, i35 or RolandV3.

The most important for me is good styles: that is, a lot of styles, editing, modifying instruments of the parts, making of new styles, styles from midi files, etc. And I prefer soft and sweet styles, not hard (rock, etc.).

In my opinion, styles from PSR740 are not so good, and variations are not really variations, because differences between A and B, C, and D are minimal.

Styles from Technics are better, more different, and variations are real variations

And Roland I dont know the new machines.

Where must I go? Can you help me?
Excuse my poor english, please.
