     If you read the ads carefully, you can avoid the cost of the
     paperwork. Get guages for "experimental aircraft" or "amateur built
     aircraft". These do not have the paperwork, are not legal on
     regular planes, but will do just fine on anyone's bus! Also, aircraft
     junkyards advertise in Trade-A-Plane, and you can get these things
     used too.
