I wanted to thank everyone again for responding to my thread. I went to the Babylock dealer, which is local. I tried out the Tiara III and I liked it. I love the throat space and it doesn't seem to be a complicated machine to learn to sew on and to maintain. It appears to be well constructed. I like that you can customize your speed, so I didn't purchase the stitch regulator. It has the programmable needle positioning needle up/down. It uses the large size capacity M class bobbin, a separate bobbin winder and low bobbin estimator warns you when bobbin is getting low. I think the dealer offered me a fair price. I also purchased the extra extension table. The machine hasn't arrived yet, but will probably be here tomorrow.
I have a lot of practicing to do. I had given up free-motion quilting because I was so tired of battling with trying to squeeze the quilt into such a small throat on my machine. It just wasn't any fun. I'm excited again about quilting.
