Don has used every brand I can think of. When I need an arranger, I use a 15 year old Solton MS-60. Frank is uber-loyal to his G-70. Gary is a Yamaha man.
What is best is what works for you. Nothing else matters.
I don't like anything Yamaha and was unimpressed with my G70.
SO WHAT ?
Play what you love, and love what you play.
Don't sweat the "small stuff".
Think about those who are gone from here. Diki, Chas and others were among those I valued...still do, actually.
What to play is all a friendly disagreement, in my mind.
It's really not worth getting cranked up about, because that's when it "hits the fan".
Fran, I appreciate the post from Diki and the gentlemanly way you have stated your position. I'm a two keyboard person, too.
It's been better around here. Let's all continue to appreciate each other.
