Welcome from Oklahoma. There is a wealth of information here. I am sure you will get an answer to your question.

Deb, welcome to the board!
I bought a Juki TL2010Q specifically for FMQ and I love it. It's straight stitch only,mostly mechanical and sews a beautiful stitch. Not pricey either.
My main machine is a Bernina but the throat space wasn't enough for FMQ. My Juki is set up just for that purpose.

I have the Juki 2200 QVP Mini which is the same machine as Susie has with different badging and a few extra feet. I bought mine for FMQ also, but I tried piecing on it and it's great for that, too.

Machines are a really personal choice. My advice is to go try out a lot of machines at your local dealership. Before you buy another machine, you might look into investing in an FMQ foot made for your Viking. They are sometimes called a darning foot.
