My suggestion on the frame is to go with the Hinterberg. It is a VERY sturdy frame and is easy to take apart and reassemble for storage purposes. I got the stretch size because I'm dreaming of a longer throat machine some day
I have the Juki TL98Q, which is nearly the same as the 2000Qi. I love the machine. Last summer, I used it to quilt a king size. With that size throat, you can expect to have only 4.5" of quilting height when you get to the end. So you have to be creative in your quilting pattern if your blocks are large. My blocks were 12". I was able to quilt this flower by quilting the bottom half in one pass and then the top half in another pass
