Keep an eye out at your local Salvation Army. Ours has cabinets often. Buyers want the head and leave the cabinet so the cabinets are sold very reasonably - I paid $1 for one and $7 for another. Be sure to have the measurements of the distance between the pins, center to center, with you. Also the base of the machine though that's not as critical.
Enjoy your new lady. They clean up so pretty and sew so well.
