It would be my main keyboard in my home studio and I like the thought of going back to an arranger to use as a "sketch pad" for its immediacy.
When I use to have arrangers, I was always Yamaha - hence me leaning towards them again. But as I said at the end, the likes of a Korg PA2X or 3x would be superb too. It's all about the deal for me at the minute. I do like the thought of 76 keys but if I'm being honest I am a bit biased towards Yamaha.....
