Good alternatives to Saturn 2

This seems good for giving mojo to sounds. Kind of refining or mixing tool more than a distortion/fuzz box (unless they add more features).

This looks very Saturnish to me - just got an email about it so no idea how it stacks up against Saturn or the other options suggested but it is on sale:

I can't say how close to Saturn it can be, but this free VST3 plugin is far from crap :

If you get an used iZotope Neutron 3 or 4, they're usually fairly cheap and similar to the FabFilter stuff?
