It is the other way around. Tin Lizzie makes the Viking MegaQuilter 18.8 and the Pfaff Grand Quilter 18.8, it is the Tin Lizzie 18ls model in a slightly different shell. All 3 of which sell for around $8000, or so. The Queen Quilter model is now discontinued, but parts and support from Tin Lizzie are still available. It is a good machine and can be found for $5000 or less, as shops try to remove them from inventory. The Empress is the Queen Quilter replacement. But I believe, the Empress is being manufactured by a different company and not Tin Lizzie.
