The Bernina frame is made by the Grace Company, if I'm not mistaken. It currently comes with the cloth leaders and side bungee clamps and is height adjustable. It retails for over $2000. It can be used with machines other than Bernina. It can only be set up at 5' and 10'-nothing in between. The ad might be a scam, so be cautious. But the frame was included with machine purchase in special promos, so it's not an impossible price. HTH
