I have seven sewing machines: two sergers, vintage Singer treadle,Singer featherweight, Bernina embroidery machine, Brother 1500, and a White machine. My old serger is a Singer, hard to thread. I bought a BabyLock Evolution this year to replace it. Wow, it is great! I quilt mostly with the Brother and piece with it too. It is really accurate and easy to use. My Bernina is the old Artista 180 embroidery machine. It does beautiful embroidery and also sews everything else beautifully. I would love to have the newer Bernina 830 or 730 embroidery machines with a larger hoop capacity. I use the other when the mood strikes me except for the treadle. I like to take the featherweight when I go on a trip. It still sews great and it was made the same year I was born. I think you should have as many sewing machines as you want or can afford.
