I have a model 27 Singer with sphinx decals - it is a treadle, made in 1902. It has the bullet shuttle, which makes finding bobbins a little more difficult, but they can be found. $35 is a good price for that machine, and you can probably get it running on your own. It could also be converted to treadle, if you were so inclined, which would eliminate the worry over the electrics.
I really like mine, and although it is in good working order, it doesn't get used much because it is in an inconvenient spot.
