Maybe you got no relation, but yep that is what the promised functionality would costs if you built it in analog and wanted to sell it with a markup that does not ruin you. If anything this is actually quite affordable.

On first glance this product contains eight potentiometers and two encoders, knobs, 170+ connectors, patch cables, a display, various discrete summers, integrators and differentiators and verly likely power rail managment that is clean enough to do actual calculations with it.

Maybe as a reality check try finding the cheapest price for 170 connectors and 8 potentiometers with knobs ; )
