I suggest a Bernina, both of mine are older models,
the 180E for embroidery and the 150QE for piecing.
Sew on several different brands and see what you like to sew on. Do some research and decide what you want in a machine.
Depending on your budget, new or used. I would rather buy a good quality used machine than a new cheaper machine.

Go with a pfaff, you can't lose. I have two one with a walking foot and the other without (but i have the walking foot that attaches). You will love the way they are made.

I've had Vikings for 34 years!!! Loved the 1977 model 6460 that is a real work horse. I bought a used Designer 1 about 5 years ago which I never did like or get used to. Sold it this spring & bought a Viking Emerald 203 which I really like. For some this may seem like a step down, but for me it was a vast improvement!!!!!!
I think the people who have said to test drive different models have the right idea. Also right idea about the new Singers not being too good. But please don't close your mind to another Viking just because you had one bad experience. Good luck with your shopping!!!!

Have Bernina 440 and love it.

I have 2 Janome machines and I love them both. Good luck on your decission!

I have 2 babylock and 3 brother....love love them had a viking...got rid of it...

I have a 20 year old Pfaff that I bought new that is a very good machine still. I bought a used Brother sewing/embrodiery machine and I like it, but if I needed a machine I would buy a Pfaff. We have a very good local dealer that provides good service.

Pfaff with the built in walking foot. I wouldn't have anything else! Jan

I love my little Janome Magnolia

My very first decent machine was a new Bernina 1031, my only machine from 1992-2000. It was a relief to finally own a machine that wasn't constantly needing to be repaired or just a royal pain to sew with.
I recommend that you bring your own fabrics and threads and test drive as many brands as you can so that you get an idea of what's available and what you want. Buy as much machine as you can afford.
You might even consider a good used machine. I've found that the older machines are often better than the new machines being made today.
