I agree with some of the above, you cannot judge B&H on the Mk III issue. Plus, I have to laugh aboout comments like "the guy was a jerk" or the "phone rep was rude."
There are rude people everywhere, you cannot judge a company on one or two calls with their phone reps. And as they were closed for passover (and for other JEwish holidays) this could explain some of the issues people have run into.
I have bought and will continue to buy my gear at B&H. They have virtually everythng I need usually in stock (OK, maybee not the MK III) they have the most competitive prices, and I have never had one problem with a return or a shipment.
