I have one similar to yours that I inherited when someone in my guild enlarged theirs. I would like a larger one but I am out of room. I love it because sometimes when I have larger pieces with lots of seams they don't want to stick like the should and I can just stick pins in it like a bulletin board.
I just took over another bedroom in my house, my DS moved out and bought a house. I was gifted an older model longarm. I plan to put a larger design wall in there someday.
