I have this bag, and I love it! It is large enough to hold the Gypsy with a silicone cover on it, the power cord, the car charger, the cartridge linking cable, the USB cord, and the cord that connects to the Cricut - with room to spare! I keep a small notepad and pen in mine to jot down design ideas or make quick sketches when I'm on the run. It has dividers with velcro so that you can configure it to suit your needs, and it has a zippered mesh pocket in the lid to hold an extra stylus or other small items. The construction is excellent, and the fabric feels almost velvety.
This bag isn't one that you'll be able to slip into your purse for a run to the soccer game, but if you are looking for an overall storage solution for the Gypsy and all of its accessories, I highly recommend it. I took mine on a recent plane trip to Florida, and I felt confident that my Gypsy was well protected.
Hallmark Scrapbook is currently selling the shoulder bag for $29.99 plus shipping on their web site. I have never ordered from them myself, but I have heard good reviews about their service. Do be aware that they are not filling orders again until January 28, as they are all at CHA!
