Honestly, you sound like you need education a lot more than advice on an air bag system. Have you ever taken an avalanche course? Do you know how to use a beacon? Do you or your friends ride with any recovery gear?
There is absolutely no guarantee that an airbag system will save your life. If you get caught in an avalanche, then you've already f-d up. Even if an air bag keeps you afloat (and there is no guarantee that it will do that), there are plenty of other ways for an avalanche to critically or fatally injure you.
Read on another forum: "If someone held a gun to my head and said, "You have to move to Salida tomorrow", I'd probably do it. If they told me I had to go to Breckenridge instead, I think I'd just let them pull the trigger."
