Todays My birthday, and I decided to splurge a bit. Bought myself a Space Navigator (used, if I really like it, I'll eventually upgrade to the pro, if not, I can resell it). It's a left handed 6dof 'mouse' for the off hand, helps manipulate 3d objects. I'll post up a review eventually. http://www.3dconnexion.com/products/...navigator.html
