I bought this same package from them two months ago. It was the best deal I could find. I can't afford a long arm right now, and I wanted to make sure I would love and use it, so it's a mid- arm. I can get 5-6 inches of quilting space with my cotton batting. They were totally amazing to deal with. Ask for Steven- he's great.
One part of the GMQ split a little bit as we were putting it together and one call to Grace Co. and we had a replacement at our house within two days.
The only other thing I bought was the leaders from Kathy's Quilting. Much easier than making your own, and you can leave them on the frame for the next quilt.
I love free motion quilting on the frame. I am not as good on a table, so for me, it's fabulous.
The only other thing I would add is that this setup does not come with a laser lite for pantograms, so if you are interested in that, you need to add it. I was not, so no big deal for me. I can't figure out how to use QuiltCAD, but again, I don't care.
I found their service to be superb, and Grace company to be incredibly patient with the phone calls when setting up.
I'd go for it. Next year or the year after I will be saving up for a long arm, but the Juki will never leave- she's my darling....
