The frame sound like it's kind of small..."a 5' free-standing frame). That's only 60" wide.........it might be harder to quilt wider quilts...unless they show an easy way to do it. I'd check it out for sure to see if it meets what you will need to quilt as far as quilt sizes. The sit-down version might be a better solution if you are restricted in space. (I'm not coordinated enough to use a sit-down one.......I have to move the machine versus moving the fabric--but some folks really can do great work with the sit-down).
Like everyone advises.....test it out, test it out, test it out at the store.
