I moved up to the 21X Elite from a 15r, which I'd had for years. It took a bit to truly appreciate the 21X. Now, having quilted 2 quilts on the machine and learning the "sweet spot" for all the settings - I'm loving this machine. I'm delighted I made the decision to upgrade...even though my 15r will always be my first love. LOL
** From my husband:
I wanted to note how well this machine was packaged and how easy it was to assemble. Using the top level as a workstation made this a seamless process. Everything was boxed and clearly labeled, and the instructions were clear and concise. Someone put a lot of thought into this and I am grateful since it made my job very easy.
