We just got back about 3 weeks ago. Used Moenkopi this time, had used PRO 3 times previous. Saved quite a bit of money, to be sure, and everything went fine. Brady is awesome, and if your group isn't huge, be sure to check in to using his "River House" thrown into the deal in Flagstaff. Nice place to shower up, regroup, and sleep the night of the day you get off. Highly recommend using as many of the pre-prepared 'Poor Boy' frozen and bagged meals, saves time and hassle. If you have big eaters in your group, it's worth increasing the amounts of the main item for dinners by at least one pound: we did and still ate every bit.
Seems like nothing is ever 100% perfect, no matter who you use, and it was the same with Moenkopi and with PRO. Minor stuff, tho, and nothing that would dissuade me from using either of them again.
We got a real competitive bid from Canyon REO, too, and had heard a lot of good things about them. In the end, it was the amount of time Brady spent on the phone with us before committing to him: he tried to cover every possible detail and option. That, and he threw in a 5th 18' Maravia fully outfitted for free. Hope this helps.
So many rivers, so little time..........
