I have 2 SewEzi Tables. I was going to buy the extension table, but for $50 more, I got an insert for another one of my machines. I have a Viking Designer 1 in one of them and a Pfaff Quilt Espression in the other. If I want to use one of them as an extension table, I can just remove the machine & set it under the table. Very sturdy and folds up & has rollers to take to retreats.
