I also do comfort quilts, no quilting for sale. I could no longer push fabrics through a machine. I originally bought a Bailey (sold it on the Bailey forum), but it is really a changed up Janome, and does not allow for the round needle that a true long arm has so there is flex in all directions. I bought a Nolting Pro on a new frame. The frame is enclosed and the large wheels move inside like butter. The handles are ergonomic and can be positioned wherever you need them to be. I have a great dealer. I do not do pantographs, but custom FMQ designs. I finally found what works for me.
Go to shows and try, but you almost need more time to try. I went to the dealers themselves and tried them out for longer periods.
