Is a Mediator 4000Di worth it?

usb2 on mediator.... yeah right!
UNLESS you already own a Poseidon USB FULL LICENCE, then you cannot register it anymore for Elbox products, and u cannot have usb 1 or 2 for mediators....
also there is no g-rex native usb driver, u need a highway or algor(pro) zorro cards, or a clockport to attach a subway to, and they all come with OEM Poseidon license...

yes, clip-on scandoublers don't really offer the full aga color range, they work with aga modes but downgrade it's color info to 16bit , that is actually OK for ECS/OCS , they usually have a color space of 8:4:4 RGB instead of the full 8:8:8 RGB... and as for videoslot scandoublers, the ones that are fully 24 bit are: the picassoIV scandoubler, the Arxo/Compserv ones v1 and v2 and the Petsoff DoubleScan4000...
