I have the Sew-Ezi table and I absolutely LOVE it. I got 2 inserts, one for my Elna and one for my Bernina. The wheels make it especially handy to take along to retreats, plus I used 2 wooden TV trays, one to make a portable cutting table (I used double stick tape to secure a small cutting mat) and the other to make an ironing table to take with me too. I just bungie them to the outside of the Sew-Ezi and wheel them along with me wherever I go sewing. It is extremely sturdy and very roomy. I've only seen pictures of the Gidget, but the machine sits in the middle of the table and doesn't seem to allow much room to the left of the needle for your project.
Right now, I have my Sew-Ezi set up in the living room to sew, since it's too hot to sew in my sewing room. It doesn't take up much room, it's easy to move to clean around...can you tell I love my Sew-Ezi??? LOL
