after a fire when I lost my old singer I bought a Brother NX450 Q It was about $800 all together. i really dislike that machine. Has a tinker toy for a foot peddle. I can't do patchwork on it . It slops off to the side every time I sew over a seam. ( well I do anyway). It insists on making an extra stitch every time I quit sewing. I finally did figure out how to default the needle position to the center after I broke 3 needles. And the 30 dollar 1/4 foot does not do a 1/4 seam.
Anyway enough whining .. I got on E-Bay and bought a 301 , the thing purrs ,straight as an arrow over all seams. I
slapped a $2. magnet down on the plate for 1/4 seams , although the plate cover has a very good marker. Wish I had my $800. back
