I just got a little black one in WalMart for 17.99. It looks like a duffel bag, but it has mesh windows on 3 sides. It also opens on the top and on one end. Seti took a trip to PA with me this past weekend and he loved it. I needed one right away and didn't have time for online shopping so I was thrilled with my find. Bed, Bath and Beyond also has one on sale in this weeks flyer.
