Congrats on the major score! Go out and get a lottery ticket too while your luck holds. You can try Sew-Classic.com for a new foot pedal. I don't know if it needs to be something special for the featherweight, I kind of doubt it. Without seeing the damage to the case I don't know exactly what it would take to fix it but at a $10 buy-in you have plenty of room to make the necessary repairs and set things up how you want them.
