That is one expensive morning's outing. Guy, if you can't afford the ponies, why play polo? Phone Linde - $240 gets a G of high purity He delivered.

No. All of the stupidity would be retained, because no-one is reliable, no-one is safe at 57 metres on air. >I know there are those of you who will say do it right or don't do it at >all - but that is ok for you. You don't have to make the choice. No-one's forcing you to dive deep. The choice you should make is not to do it 'till you can afford to do it safely. Do shallower dives - ones within your budget. Or get a better paying job or a second income.
