Whew! 67F stall warning lift detector switch Safe Flight Instrument Corp. part #46001 replacement cost of 1800 bucks at Spruce is the worst stupid aircraft part price i've ever seen.  I wonder what Safe Flight's reasoning is?  I may call them and ask come Monday. I have 2, one that will never sound the horn, one that will never stop sounding the horn.  I'm going to try to fix them, but was looking for a reasonable replacement. Any ideas or reasonable work arounds? Thanks Gary
