Only problem with Vodka/Sugar/Vinegar is you have to dose it every day, and if want to do something like take a vacation you are sort of screwed unless you have someone you can really really trust to dose for you. Biopellets require almost zero attention once they are set up.
On a side note I see Oceanic has a kick ass deal on the NPX pellets
