I'm real sorry about anyone loosing a friend or family member in an Avy (I couldn't imagine the pain). But getting mad about the price of avy gear is pure ignorance and childish.
I've owned a number of small businesses, so I can relate to things called OVERHEAD, PROFIT MARGINS, LIABILITY INSURANCE, TAXES, WAGES, RETURN ON INVESTMENT, RETIREMENT, GOVERNMENT REG'S, etc. I'm amazed that businesses that cater to back country users can even stay in business. It's not like everbody and their dog is required to go play on an avalanche hill. There are a select few who choose to go play on the avy hills, and you have to pay to play. When a business has a limited base of customers, in order to stay in business and service what customers they do have, they must charge prices that seem "high", or "ridiculous", or "extreme", to make a profit. I don't knowingly take risks on avy prone hills, so I have chosen not to purchase an air bag. I also know that my 700 won't outclimb the 8's, 1000's, and turbos, so I don't have anything to prove by climbing a hill that could be dangerous. If you are not willing to pay the price for the extra equipment, stay off and away from the hill. I have a beacon, shovel, and probes and hope I never need them.
