Zero import duty for me neither to France, so a pretty good deal, but maybe I’ve just been lucky ? (Wilzyx declared 75$USD as value for me, that may be the upper margin before taxes).
He gives 20$ to O_c developpers for each module sold (they confirmed it in the muffwiggler thread), so even if you have to pay import taxes it should be approximately the “common” price, maybe a bit more (~240€), but you’ll suport the work of the creators and futur firmware updates 
I agree there’s quite menu diving for certain apps, but it offers so much in little space!
I just discovered you can scale the LFOS in Quadraturia to turn them unipolar without external offset/attenuator, just with two menu options (gain/offset), you can also attenuate incoming CVs and save your attenuverters/offsets for other things!
