I believe it.
Coincidentally it was my desire for the Keys that sent my first A4 out the door.
I was able to sell and buy up for about $100 difference which was a good deal at the time.
I was less productive with the Keys since I am not much of a keyboard player, and more of a programmer. So ultimately the Keys left and other things filled the gap.
It will be good to have an A4 again.
