I wanted to see by myself.

Currently (08/08/23), there is a second-hand 'Make Noise MATHS V1 Silver/ Red Knobs' offered at 1100€ at Reverb. That same day, a new MATHS at Thomann (or Music Store, or elsewhere) costs 333€.
So today, we can estimate the price of nostalgia for this module at about 767 €...

I decided to preciously keep my good old passive multiple A-180-2.
