I bought one. I really like it. My mother bought one after she seen mine. She has not got hers set up yet.
I will tell you..if you do get one. Get regular wood for the runners. I got what he suggested (MDF) and they bend...so I am going to get pine 1x2's instead of the ones he recommends.
other then that it was fun to use. I have only used it on one quilt so far...got it less then 6 months ago..but I have three quilt tops waiting for me to use it with. I have to set it up on my kitchen table.
