Here's a view of the gear I use for small batches, a bit cheaper than Ford Forgotton's:

The majority of this gear is for the titration- the test of the used oil which tells you how much lye to use- and for making a 1-liter batch of biodiesel. The 'reactor' is the juice bottle on the left, the measuring devices are the kitchen measure and the '**** syringes', the 'methoxide reactor'/methanol measuring glassware is the Mason jar with the white tape on it (for knowing how far is 200ml methanol), the 'phenol red' from the hardware store or the pool and hot tub store replaces the pH meters in Darryl's photos, yellow bottle HEET= methanol and red bottle HEET = isopropyl alcohol for titration.
