If it's just another old electric sewing machine, no, I wouldn't pay that for it.
After Cari said it was electric, now I see there are no holes for the belt (holes should be under the hand wheel on the bed of the machine). If it has no irons inside the cabinet, it cannot be converted back to a treadle (if it ever was one). I bet it would be very difficult, if not impossible, to find a set of irons to fit that cabinet.
