I have one and use it. Have my 'quilting machine' set up on a 6 foot banquet table in my spare spare room....
I do not make any thing bigger than a twin, so it works fine for me....
There is a learning curve...that you kinda have to get thru....you have to 'learn' how to attach the backing, batting and top to the rods....but once you do a couple ....it works well for me....
I did buy mine used at a far reduced rate over full price....and for what you get it works for me.......
