I looked at the ROS65VC as well and it's a great piece of engineering, but opted for the 1250devs because I am planning on doing some sanding with built in cabinetry/paneling and liked the ergonomics for holding vertically at eye level. The power rotational mode (i.e. grinder time!) is the real deal and it removes stock fast when needed. Thanks! I'd love to say a Festool CT26...but alas, I currently have a standard 5G shop-vac wtih HEPA filter and drywall collection filter bag. It does the job, but an area where I am doing more research for a future purchase.
