Great topic to be thinking about & discussing.
There have actually been a couple of other "incidents" and interesting trips already. Check out these threads at TGR:

The places to start:
1) Take an Avy 1 class.
2) Read stuff. Check out the slide zone at TGR. Check out www.avalanche.org, www.beaconreviews.com, www.wildsnow.com,
http://avalanche.state.co.us/index.php, and so on. Go to Amazon & snag Staying Alive..., etc...
3) Get connected to informed, experienced, good people.
There are a ton of good equipment options. None of which matter one whit without the right knowledge & companions. Mostly it makes me pretty cowardly. In a good way... I think.
After some reading, preferably a class, and some messing about, you'll sort your equipment opinions appropriately.
