I am considering buying a Grace Majestic quilt frame and am wondering if anyone here already owns one or has ever used one. If so what are the pros and cons?

Thanks in advance!

I'm considering this because the woman who usually quilts my tops for me is always backed up and I have to wait forever to get them back. I just figured it would pay for itself in the long run and maybe if I became comfortable enough to quilt for others I could make a little money. Let me know your thoughts
