Brake Light Switch

The brake light switch on my wife's 1969 Sprite stopped
working this weekend.  I replaced it last year with one from
Moss.  Can someone steer me to a better supplier for this
part?  This is the mechanical version.  I am thinking of
inserting a pressure switch into the brake line (rear,
probably).  Has anyone else made this modification?
Pressure switches seem much more reliable, and are so much
cheaper, too.
