The size of the keys on the PA50 are fine-it's the sturdiness of the keys that is the issue. The keys feel-in my opinion too light, and may be an issue for someone that likes very sturdy keys. My biggest issue-so far is I have a hard time hitting the fill buttons-for some reason I initally go for the Intro, or Ending buttons instead. Maybe I can program a footswitch to do the fills.

This is something very important for me.
You may see a difference of 1 inch along the 5 octaves.
