With my limited sewing experience, larger harp/throat space makes sewing on any project so much easier. I had a Bernina B215 that I've been using for 7-8 years. I really struggled with large projects, to the point where I didn't want to finish the project. Simple queen size quilts, thick, bulky bags, etc.
After joining this group and asking advice, I bought a Brother 1500. I absolutely love it. The harp space being wider and taller has made my sewing so much more enjoyable. I've been having so much fun with it. (I have also started to dabble in FMQ, never thought of doing that before).
I bought my Brother through Walmart for $479 a couple weeks before Christmas. Amazon had it for the same price. Good Luck and have fun!
