Good job on the workout Richard!
I've rented the Dragon, a few times, the people that say "my own way works better" have not tested on a real job for a few hours to really know how it works. I've done the "other ways" for years, and "this way" w/ the Dragon cuts the time in half. I did a job w/ the Dragon that was over 800 square feet in 2 hours, included sweeping the floor, dragon w/ squeaky and ift, than matte finish one coat. If you have 2 guys doing the work, you can discount the price a lil bit and still make $200-$400/hour.
