Thanks for starting this thread...its very interesting and has some great information. I have quilted all of my quilts..(including several large size queens) on either my old Singer or my regular 200E Bernina. I don't have any trouble really moving it around (and Tim...I"m 5', 110 lbs.)
I guess its what you are used to. I'm sure that if I tried one of the larger machines, I would never do one on my regular little machine again! I know that I would LOVE to have a mid-arm at least some day, but for now...I'll just bookmark this thread for my beginning research.
