Pricewise, for 10 x 100 or 110 mcg. of LSD, BrainCandy and ProfessorFarnsworth are tied at 30 USD. So that's nice.
Not_Ron_Paul is slightly more expensive, at 35 USD, and Tokenshire (who re-sells Gammagoblin's "Parvati's Tears") is the most expensive of the four, at 40 USD.
So: Who'd ya recommend?
Brain candy all day everyday. My only guy
