I had a Singer Touch N Sew from the 70s as my first machine. I bought a "Bigfoot" from Keepsake Quilting. It was my first quilt related purchase. I then realized I needed a walking foot. Bought one. Loved the difference it made in my quilting! However, the feed dogs did not go down on the machine.
So, I "retired" it to my DD who needed something for mending. And I bought a Juki 98Q. It came with the walking foot and darning foot (yippee skippee) and the feed dogs go down. But THE BEST thing- the little scissors that cut the thread for you. I am in heaven.
My quilting is so much better. Someday I will make room for the frame I bought last year and out the Juki on it. Right now I use the 8 foot table for cutting, etc. Actually, I don't think I have enough room for the frame in the room.
