We also have the Z-Street and are very happy with it. I find the 2 handles are great as well... my diaper bag fits nicely over them so it's a great way to carry it without taking up more space. What's more, the airline damaged one handle grip, and Zooper is sending me a new one. Great customer service!
Also, it folds up to a very compact size, and fits into a small trunk. The hood could be better, but all in all, we're very happy with the Z-Street as our unbrella stroller.
