congrats! I just got a 503a and am in love with her. I woke up at like 3:30 in the morning the night I got her with the name Liza Jane in my head....so Liza Jane she is! She replaces my newest (agewise) machine which was a 12yo kenmore that the computer died in. I am going to try fmq on her as soon as I get a foot but it may be a couple weeks before that happens......:-(
