and that was 1999! Granted, their volumes are much less than 10K, and I
think that the chip used in the device is the 4394, not the 4356, but I
seriously doubt that the component cost is anywhere near B&D's $200-$300
"SOTA" estimate since the design isn't SOTA and the engineering cost has
long since been amortized. I didn't see any other components that looked
particularly expensive, the printed wiring board is 2-sided using surface
mounted components, and the closest thing to a device containing software
is a Altera PLD. I also noticed that the analog output traces run a little
too close to the power supply's voltage regulators for my taste, even
allowing for the fact that they're differential.

The question, then, is, how much is their Bill of Materials? How much did
they spend on R&D, how much did they spend on software, and how much on
mechanicals and interconnects?

To be able to charge $1000 the BOM, by all rights needs to be about $200-300
all tallied up.

Perhaps the A to D converters are $10/each in the volume they are likely to
buy, the other chips and code, PCB's and so on -- what is the cost?
