I am not extremely familiar with the Insta machines, but have had a chance to operate one at a show. From first glance it looks like a quality machine. My only dislikes are the single handle design, makes it tougher to lock down than a shovel handle design. And I believe that a pin needed to be inserted after locking the press down to hold it into place (can someone verify this?). It might have been on just the model I was using, but it would be worth asking the supplier you plan to purchase from.
