What's cool about the Alexandra Knight bags is that they're custom made for you. Here's a review from The Gadgeteer that describes the process of ordering, which includes specifying things like the hide, color, length of the straps, type of lining, etc.. Very cool (and expensive if you want alligator).
I really, really like the Taylor Tote, but would want longer straps and maybe get it in a brightly colored ostrich (as in the review, ostrich would be "only" $3200 rather than $5500 for alligator).
