I am very satisfied of the sound quality of my VA7; the styles are very good, with long intro/endings and loops usually lasting longer than 4 bars; if I don't like a style I can always use a converted/imported one.
I have tried other boards too, but I will keep my VA7 until the next generation of Roland arrangers comes out (hopefully with a hard disk, a lot of buttons and a real sampling ability).
