[squarefoot]

I'm not sure about the 3rd Ed, but the 2nd Ed had a much cheaper edition in a red soft cover and slightly smaller size, presumably cheaper recycled paper and no bells and whistles. It was distributed in India and developing countries and by all appearances it was totally legit, also accompanied by a label forbidding the sale in "western" world, where presumably they wanted to adjust prices to the higher income. Of course it was just a matter of time before it would land on Ebay sellers pages and elsewhere. There is where I got mine; items photos however showed the original so I was buying in good faith, although I should have recalled that old saying that if something seems too good to be true (had a very low price) it usually is. From what I can recall from my copy, there were no errors or omissions compared to the "official" one.
