I'm sure you both have used the current Canon extenders, the II's, to make your comparisons when you say "every bit as good as". I wonder what makes the Tamron more versatile? As far as cost, I recently sold my old Canon 2x for 20% less than I paid for it. In the long run, when you consider resale value, trade-in value or even the ability to sell at all, I wonder how much you save, if any? How sure are you that the new 500 f/2.8 IS lens will work properly with the Tamron while attached to your new 1D? Don't you get tired of sending it back for retrofit? And last, when someone ask you what you're using, do you say Canon or do you say Canon/Tamron/Tokina?
My 2 cents.
