I've also been on the Steamboat Powdercats operation. I had one of the most epic days of skiing in my life on Buff Pass- just sick. Over 4' of champagne. One of my buddies is a guide for them, and I know a lot of the guys that work there- they're good people. Truly, a quality company and worth the money. They emphasize safety, but they don't hold back terrain unless it's really dangerous.
They also offer a very reasonable Avy Safety class
; run also on Buff Pass from the cat. The machine allows then to get you right to good location for digging test pits, and the tracks really simulate an avalanche deposition zone for beacon practice. I think a couple of Buzzards have been on it- Dave Frank went last year, I think. I did mine 2 years ago.
I've wanted to check out the Monarch operation as well, but I haven't gotten around to it.
