Two important things to consider....are the rails sturdy and will they bow in time? That is killer. Once you roll your quilt a few times, how much actual quilting room is left? The roll of the quilt take up quite a bit of room, and this can squelch any creativity you may have. I started on a Pfaff frame and viking mega quilter machine, and I became very frustrated very quickly. That was in 2006, when I purchased my A-1 longarm and never looked back. The home frames have very little quilting room once you get into the middle of the quilt...unless they have improved significantly.
