I use my Pfaff 7550 purchased in 1996. It is the only sewing machine I have. I set it up with a FMQ foot and as long as I use a quality thread, it works great. Would love one with a longer throat but cannot afford it. Mostly what I do is lap size right now.
My husband did make a table for FMQ for me. It is made out of insulation board that is cut for my machine to sit into. The board is covered with very heavyweight plastic. That provides a surface that allowes the quilt to slide easily.
