I currently own the Metabo 6" ROS, which I like a lot. But have been thinking of taking the plunge with the Festool Rotex 150. But first I have a few questions.

I read about Dual Mode. Are these two modes, Rotary and Random Orbital? The first for more aggressive sanding and the later for fine sanding?

Also, it seems that separate pads are required for sanding. Not simply discs, but “Tool Free FastFix Pads”. This true?

It seems this can also be used as a polisher, could this in fact replace my possible purchase of the Porter Cable 7424.

Lastly, is there a better place than others to buy Festool? I know the price is fixed, but some place online with no tax, free shipping, or here is a thought, great customer service?
