Helium or nitrogen is much cheaper and easier to acquire than barbiturates. The drawback is dying with a bag over your head and your hands loosely tied to the bedpost. In about half the cases where the client decides on inert gas, there is an unconscious instinct to rip the bag off the head after falling unconscious. It's impossible to tell who will and won't do this.
It's important to remember that helium is a non-renewable gas. Certain suppliers are no longer filling their tanks to full capacity, and a few are beginning to add irritants due to the increased use in suicides. It's best to use two tanks in unison attached with a T-junction. Check for leaks with soapy water.
