Thanks for the information I really appreciate it. I have a Bernina 550 that sews through bluejeans pretty good (enough for mending) and it will do light weight leather as well but tends to skip stitches so I would like to get something a little more heavy duty. Debating if I should save the $150 on the zig-zag stitch and use that on the Monster II Balance Wheel for more precise stitches? I think that will probably be my route. Thanks Again - K
