It Bit the Dust

I have had to finally give up on my  my mother's old Kenmore sewing machine.  Apparently my mom and grandma split the cost when I was a baby.  It definitely needs a tune up before I return it to my mom and I think it will go back to working fine but for now I need to use a better machine.  It has stopped zigzagging and now it will not even straight stitch.  There is probably an easy explanation for this but I can't figure it out.  I am now using a Necchi.  It is OK but change sucks!  It is still faster to figure stuff out on this machine than screw around with the Kenmore every 20 minutes.  I really want a Pfaff,  cash donations are welcome!
