My machine at home (USA) is a regular old fashioned Singer 401, but my hubby allowed me to bring a wonderful machine with me as we traveled abroad. I have an Elna Heirloom etition with a quarter inch foot for quilting seams. I could not ask for anything better.
If I were going to suggest something for a "full time" quilter, maybe the stronger the better. I continually have to fear what will happen to my Elna, not because it is inferior, but because it endures tropical heat and humidity all the time. Literally everything deteriorates in the tropics. If I had my choice, I probably would bring the old Singer to die here rather than my new, precious one.
