Absolutely go for a sit down. It is way better on your body than standing for hours and yes, just practice, practice, practice. I offer to quilt charity quilts for my guild quilt cupboard on my Sweet Sixteen and get to try lots of different things without great anxiety. Ask the dealer if you can take one home and try it. My dealer let me do that and of course she knew once I had it I could never let it go. It was a demo machine so got a nice discount. I also did not get the stitch regulator and never regretted that decision.
