Bill, Very informative series of photos with explanations. The bristle disk looks like it's off my list. I think that I'll take some time to strip a portion of my cab with the Wagner just so you can see how it works and how fast it works. But instead of big chunks I'm going to wind up with dust and I don't have anywhere near the amount of surface to strip that you do.
Denny, I got mine at Home Depot and it was $79.95 plus 7.5% tax... and that price includes a $15 disk... which lasted through a hood, two front fenders and most of a gas tank, which I forgot to mention earlier. It would have laster longer if I hadn't loaded it up with the gooey paint on the gas tank.
I found that being able to hold it with one hand came in handy on several occasions when I had to use my other hand to hold a part, like when I just laid my fender on some saw horses.
