Our group went through Brady and Moenkopi for our trip down the Grand Canyon last April 2007. We did a 21-day trip from Lees Ferry to Lake Mead. Brady supplied three 18-foot rafts, equipment, and food for 16 people. All the logistics were handled very well and I would recommend them, i.e. I would use them again. The only thing I would warn against is to check the supply of food. In general I would say the menu was light and more than one night people went to bed hungry. I would say to definitely check them out but be sure to do your own checking into the menu and amount of whatever is provided.
Have a great trip!
