Can I say "ANY?", lol? I just got a used Bother embrodery machine....an I can tell you, its So user friendly, even for a computer dummy like me.
I love the oldSingers, but I have a few old Japanese ones, too, one is a bight turquise! Just love the pretty colors.
GF has a tiny Janome, its so pretty and light, and she has never had to repair it, would LOVE a tiny one someday. Or a FW!
SIL has a beautiful Pfaff......SO, I guess I dont have a favorite, just LOVE machines.
Oh, and the Necci I got for 3.00 at a garage sle runs like a charm!
