WVO filtering - Is a centrifuge worth it?

[Watarski]

I am trying to plan out my WVO filtration setup. I have read 2 different ways to filter as it goes into the final holding container - 1) Use a 1 or 2 micron filter (gravity or pump?) or 2) Use a centrifuge. I have read where a centrifuge is good enough, and I've read where some people found better results when running it through the centrifuge twice. Should I save the $500-$700 on a centrifuge/pump combo and go with the 1/2 micron filters? Do the filters get it clean enough? Thanks for the help
