I have a commercial grade Singer machine that I use for all of my regular sewing including constructing my quilt tops.
I have a Juki TL-98Q that my DH gave me for our 25th wedding anniversary with my Gracie setup. I can't imagine wanting or needing any other machine short of a long arm.
I have seen many posts showing people buying many machines. Why? I understand hording fabric, magazines and even patterns but machines? I understand two so I don't have to move one back and forth off the quilting frame.
