I'm loving the reviews I hear about the 2010q, but I'm not sure I could live without the zig-zag feature...or more precisely to the ability to shift the needle slightly left or right. I adjust my needle position all the time to get a good 1/4inch seam, but also to get the quilt edge on both feed dogs when I sew something on like a binding. I also use the applique stitches on my cheapy brother too.
For those of you with a 2010q are you able to do all your piecing etc... on it?
