I tried out long arms at shows and then got mine through the mail from Sewing Machines Plus. They ran a special -- 18" Queen Quilter, frame, laser, shipped for $5000 and they finance. I buy the rails at Home Depot (electrical conduit) and cut them to the size I need. The Queen Quilter is a Tin Lizzie and the frame is made by Grace.It took my nephew and I a weekend to set it up, and yes, it takes a lot of room, because you will need to walk al the way around it. A king size did not fit into my 10X14' room. The computer would be another $5000 -- go figure when you can buy a capable laptop for less than $1000. It also comes with a CD to show how to assemble it and leaders (that you put on the rails and pin the quilt parts to). Just another option to consider.
