I like the Daessy rolling mount as well. It is the one that Eye Response Technologies offers as part of their Combo mount option.

 

 

This is the rolling mount I used- (Daessy rolling mount). One of the things that’s nice about it is that it’s lightweight, so it can easily be moved from room to room, or carried upstairs, taken outside, etc.
