I have the larger "supreme slider" and I like it - makes things easier.
However that said Laura Coia of SewVery Easy did a presentation to our guild a few years ago. She has all kinds of tutorials on YouTube for lots of quilting projects and sewing hacks. She suggested using a "snowcarpet" that kids use for sledding. It is a thin strong plastic rectangle that is big and easy to use. I went out the day after the meeting and found it at the dollar store and bought two. Works great, so easy & inexpensive! Just be sure to follow her tips and tape it down so your project doesn't get caught on it.
Here is her YouTube video showing how:
