I love-love-love my Gracie Z44 frame ~ I can put it up when needed, and take it down and put the sides in the closet & the poles in the corner when not needed. I remember getting it online for around $350? It's been a few years.
If she wants a smaller size frame and has room for a square frame you sit at, I remember seeing a PVC framework at JoAnn's ~ wait until its not on sale & use a coupon (ha ha 50% starts in a few days)... That gives about a 2-3 foot working area?
