PA300 vs Yahama S670 vs Roland BK5

[alexthepenguin]

I'm hoping to buy my first arranger keyboard.

Quick background: I'm trained as a classical pianist and organist but have never really played on an arranger before (well I mean I have but I was just using it as a keyboard rather than any of the functionality it offers).

I'm thinking more of a beginner level arranger and I'm undecided between PA300, s670 or BK5. These all have similar prices and relatively similar features so I'm wondering if you could perhaps let me know the pros and cons of each one and perhaps recommend one to me? Also feel free to suggest other options.

Thanks!

All I know that aall the people who bought yamaha and roland sold their keyboards to buy a KORG, KORG is the king.

I have played on psr-s670.this keyboard has Dj styles and some nice synths but organs are bad for me.s670 is a plastic for me.
