My Supreme Slider is about 20 years old and I'm still using it. I bought the biggest one and it does make a difference in the ease of moving the quilt. I also won't machine quilt without Machinger gloves. You can fmq on any sewing machine that works. One thing I have learned over the years of machine quilting is if your machine isn't up to the task you will lose before starting. Many of the computer new machine the whole foot will move when the quilt is tugged to the left or right. Check that out so you know exactly how aggressive you can be with the quilt and design. I do all my own machine quilting using ruler guides or free motion. Edge to edge is the best way for me, no thread ends to hide. It's fun and saves money too.
