Honest, I love my Genos more and more for each day it's getting powered up. (Not bad for an 'anti yammie' like me.)
In my ears, it's the best sounding arranger made by Yamaha till date, and as I see it today, it will not be swapped for any other arranger.
But, I will add a Korg PA4X-76 or the next TOTL Korg the day I'm in the mood to spend some money from my saving account just to please myself.
After that's done, I can not see any reason for me to replace any arranger unless it explodes or cannot be played any more ....
Edit/Added:
The only thing I dislike very much is the 'plastic fantastic' feel when move or lift Genos.
There is no way it can be compared to G-70, SD1. Not even T4, those feels much more solid than Genos.
Yeah, it's light weight, but feels pretty cheap until you start it up....
