Digital read out static meters

Why are these so expensive? They should be under $50.
Easy solution. Don’t buy a meter.

Do you know what goes into one? ... the BOM cost at the quantify manufactured? How about the amortized engineering costs? tooling costs? Sales and marketing overhead?

Do you work for free?
they were available as science  kits in radio shack without the digital readout( which should lower the cost even further).
