I quilt on a mega. Have about 41/2 to 5 inch quilting space. When I started FMQ it was a great beginner machine. I still use it, just use smaller width pantos. I would love a bigger machine but can't afford it so will stick to my mega. I have never had any problems with it. Mine will use any brand of thread and in 5 years I have never had to adjust tension (knock on wood). The price is great, I paid much more. Can't say about frame, mine is on homemade frame. I have done all sizes including king with mine.
