Thanks for the input! I plan to piece as well as quilt with the machine. I do meandering and freehand patterned quilting as well as straight stitches and stitch-in-the-ditch. I didn't know about patternreview.com - thanks - I'll look them up there.
To answer Candace, I won't be sewing 8 hours a day or anywhere near it. I plan to make this a half-time job.
Thanks to everyone for the good input so far!
