It is well written and extremely informative. For example, in Hong Kong restaurants a carbon steel wok has a useful working life of approximately two weeks. The compressed natural gas burners used in these restaurants put out 150,000 BtU - that's the rating on my home's furnace - which begins to melt the carbon steel, thinning it out until it gets thrown on the recycling pile.
If you're serious about Chinese cooking and "wok hay", I'd recommend an Eastman Big Kahuna propane burner. For outdoor use only, it puts out 55,000 BtU and gives you a chance to get that elusive real taste at home.
The Big Kahuna is available online (got mine at Amazon) for fifty bucks, imho the best bargain of 2005...
