I am looking at all of these, and can't decide. I would like to know if anyone has either? The first 2, are suppose to be basically the same machine, about the same price, etc., and both made by the Grace Co. Kathyquilts, are the only one that sells the Block RockiT. She said they give lifetime support. I also found one called King Quilter Special Edition 18x8 Long Arm, I found it here, http://www.sewingmachinesplus.com/ki...al-edition.php, there isn't alot of price difference in them, but the last one has alot more options. Anyone ever had one of these 3 machines?
