I have several rolling cases and my favorite is one that I bought at Walmart on Black Friday several years ago. I went in the afternoon when most deals were gone. The brand is something like "Everything Mary" . The trolley has a large pocket on the front which I use for surge protector and extension cord. There Re two pockets, one on each end that are about 6 X 7 inches. There are 3 clear zip pockets on the inside of the lid. The top kind of folds down and zips, it is rounded. It is my absolute favorite. I use it at least once a week. I bought it for the princely sum of $25. They had the same deal last year too. I like it lots better than the one I bought from Joann's.
