D-Limonene is available in various stores in oz - do a google search, its easy to find!

Toluene is sometimes available form hardware stores and is quite good quality. Unlike Xylene from bunnings, which tends to leave a bit of residue.

Toluene is not THAT toxic, just wear a mask or avoid sniffing and you will be right.

Shellite seems to be SHIT these days... friends have been going for buying Zippo instead which works a whole lot better for recrystallisation etc. Try doing two shellite pulls and then a toluene pull, the toluene will normally pull more than the first two shellite pulls!

Once you go d-limonene, and figure out how to make it work for you, it is hard to go back to the chems!
