Try one out. What I love about it is that it looks nice, and that you can set its shuttle speed to a maximum amount, meaning you can set it to something like 40fps, which is great for scrolling through dialogue while still following what is being said.
However, mine goes unused most days. I’ve been using Avids since 1996 or so, and my right hand is on the mouse and my left is on the keyboard. I need a third hand to operate the Artist Control.
