I agree with your sentiments about price+warranty+IS, Marsu, but when a reviewer has to purchase two retail lenses, then have one of them replaced by Tamron (bringing the tally up to 3 lenses) in order to get one that focuses properly - I don't like those odds.
5D Mark III, 40D, 1V. Bunch of strobes, lenses and other bits.
They're, their, there, it's, its, too, to, than, then, you're, your. One lens, two lenses, the lens's aperture.
